Jakarta, Indonesia (CNN) — Hundreds of Indonesian police officers charged into a prison in Bali on Wednesday to subdue rioting inmates who had set a building on fire and thrown stones at firefighters.

The police arrived at Kerobokan Prison late Tuesday to ensure that no prisoners escaped during the rioting, said Ketut Untung Sayoga, the deputy chief of police in Bali, but did not enter the facility until daylight broke Wednesday.

Three inmates were wounded, one of them shot in the leg by a rubber bullet, Sayoga said.

The riot took place in a separate block from the one housing foreign inmates. None of the 60 foreign prisoners were harmed, Sayoga said.

The prison is where Schapelle Corby, an Australian beauty therapist convicted in 2005 of smuggling nine pounds of marijuana into Bali, is serving a 20 year prison sentence.

The 12 Australians in the prison were unharmed, said Ray Marcelo, a public affairs official at the Australian Embassy in Jakarta.

Kerobokan Prison is in southern Bali, a few kilometers from Denpasar Airport and the popular tourist area of Kuta.

It appeared to be under control Wednesday but remained heavily guarded.

London (CNN) — The deaths of two Western journalists Wednesday in Syria — where at least three other journalists, including two Syrians, had already been killed this year — highlight the danger reporters face in covering conflict zones.

Marie Colvin, an American veteran foreign correspondent for London’s Sunday Times, and prize-winning war photographer Remi Ochlik, 28, were killed in shelling in the city of Homs, the besieged center of resistance to President Bashar al-Assad’s regime.

Colleagues remembered Colvin, who lost her left eye to shrapnel while covering a conflict in Sri Lanka, as “a legend” and “a class act.”

Ochlik had covered conflicts from Haiti to Libya, and he won first prize in the 2011 World Press Photo general news category for a photo of a rebel fighter resting in front of a rebel flag in the war-torn landscape of Ras Lanuf in Libya.

The French Foreign Ministry demanded that Syria give the International Committee of the Red Cross access to Homs to remove their bodies.

At least one other journalist, photographer Paul Conroy, was injured in the attack, the Sunday Times said, adding that initial reports suggest his wounds are not serious.

Their deaths come less than a week after New York Times reporter Anthony Shadid, a two-time Pulitzer Prize winner, died in Syria, apparently of an asthma attack.

Rupert Murdoch, the media magnate who owns the Sunday Times, said Colvin “put her life in danger on many occasions because she was driven by a determination that the misdeeds of tyrants and the suffering of the victims did not go unreported.”

And John Witherow, the editor of the paper where she worked for more than 25 years, said Colvin “was much more than a war reporter. She was a woman with a tremendous joie de vivre, full of humor and mischief and surrounded by a large circle of friends.”

Asked about calls in recent days by Sens. John McCain, R-Arizona, and Lindsey Graham, R-South Carolina, for the United States to consider arming the opposition, Carney said, “We don’t want to take actions that would contribute to the further militarization of Syria, because that could take the country down a dangerous path.

“But we don’t rule out additional measures that, working with our international partners, that the international community might take,” he added.

U.S. State Department spokeswoman Victoria Nuland held out hope for a political solution, but she too cited the possibility of seeking “additional measures” in the absence of change.

“From our perspective, we don’t believe that it makes sense to contribute now to the further militarization of Syria. What we don’t want to see is the spiral of violence increase. That said, if we can’t get Assad to yield to the pressure that we are all bringing to bear, we may have to consider additional measures,” Nuland said.

While foreign officials spoke, Syrian government forces pounded the embattled city of Homs for the 18th consecutive day and tormented residents in several other cities, opposition activists said.

About 9,000 people have been killed — including 106 just Tuesday — since the government crackdown began almost one year ago, according to the opposition Local Coordination Committies of Syria.

At least 55 people were killed in Idlib, 45 in Homs, three in the Damascus suburbs, two in Deir Ezzor and one in Aleppo, the LCC said.

The Revolutionary Council of Homs said shelling blasted through homes in the city’s Baba Amr neighborhood, but “the number of those injured could not be estimated because of the nonstop bombing,” it said.

“This attack carried out by the Assad forces can be considered a real genocide, and all this is happening amid an electricity, water, and communication services outage, accompanied by the unavailability of food, baby formula and medicine. In this manner, even those who may survive the bombing, end up dying due to hunger or lack of medical care,” the group said.

But the state-run Syrian Arab News Agency reported Tuesday that “food and services are available in Homs,” and said “provocative channels are fabricating lies” to the contrary.

CNN cannot independently verify opposition or government reports of casualties because the government has severely limited access to the country by foreign journalists.

But the vast majority of accounts from inside Syria indicate al-Assad’s forces are slaughtering civilians in an attempt to wipe out opposition members, who are demanding his ouster and democratic reforms.

Colvin, in her interview the night before her death, described the heartbreak of watching a young boy die after being struck in the chest by shrapnel — one of the many children killed in the conflict.

She said it was important to share his story and images.

“That little baby is one of two children who died today,” Colvin said. “That baby probably will move more people to think, what is going on, and why is no one stopping this murder in Homs that is happening everyday?”

(CNN) — A bullet thought to have been from a shootout between carjackers and municipal police in Ciudad Juarez, Mexico, struck a woman walking in neighboring El Paso, Texas, Tuesday morning, El Paso’s mayor told CNN.

The still unidentified woman, 48, was shot in the lower leg; her injuries were not considered life-threatening.

El Paso Mayor John Cook said local police investigating the incident had not officially confirmed that the bullet came from Juarez, but they were “treating it as if it did,” he said.

“It’s still matter of speculation,” he added.

“Early on, it became evident this may have been a stray bullet rather than a targeted shooting in downtown,” local police said in a press release. “The El Paso Police Department continues its investigation and is working closely with its counterparts in Mexico.”

If the bullet did in fact come from Mexico, this is “the first time a person has been hit” in the 3½ year since drug-fueled violence escalated in neighboring Juarez, Cook added.

In Juarez, a shootout between suspected carjackers and the municipal police happened around 11 a.m. (1 p.m. ET), about the same time the woman was shot, according to municipal police spokesman Adrian Sanchez.

He was unaware of any connection between that shooting and the incident in El Paso.

“We have an office that works with the U.S. and so far we have not received a report from them saying the two incidents were connected,” he added.

El Paso police said that while they were responding to the shooting, the El Paso 911 center “received numerous calls advising of shots fired near the border in Juarez, Mexico.”

Just about a mile separates downtown El Paso from Juarez.

“Under the right circumstances there is a possibility that a round fired from an AK-type weapon could travel that far, conceivably,” Mike Brooks, HLN Law Enforcement analyst told CNN. “It depends on what kind of round it is and how heavy the round is.”

“We’re advising the citizens of El Paso that this is an isolated incident. We don’t want people to start panicking,” he said.

At least four schools in El Paso went on lockdown shortly after the woman was reported being shot.

“We were alerted by local police about concerns in the area,” Estela Reyes, the press officer for the La Fe Preparatory School, told CNN. “We were in lockdown by 11:30 a.m. and lifted it about 30 minutes later. The kids were never in any imminent danger,” she said.

Reyes said her school is about “seven or eight blocks” from downtown El Paso and she never heard gunfire from Juarez.

In June 2010, the El Paso City Hall was struck by several rounds, which local police believe the shots may have come from a shooting in Juarez.

About two months later, a similar incident occurred when a building at the University of Texas at El Paso was struck by a bullet. School officials believe that round also came from a shooting in Juarez.

(CNN) — Two days of talks with Iran have failed to produce agreement on how to verify that Iran’s nuclear program remains peaceful, the International Atomic Energy Agency announced Tuesday.

Iran also refused to allow a team from the U.N. nuclear watchdog agency to visit its military base at Parchin, southeast of Tehran, during the two-day visit, the IAEA said.

“Intensive efforts were made to reach agreement on a document facilitating the clarification of unresolved issues in connection with Iran’s nuclear program, particularly those relating to possible military dimensions,” an IAEA statement on the visit read. “Unfortunately, agreement was not reached on this document.”

The high-level team of experts was on its way back from Iran late Tuesday, the agency said. There was no immediate comment on its account from Iranian authorities.

Iran says it is producing enriched uranium to fuel civilian power plants and has refused international demands to halt its production. But the IAEA reported in November that it had information to suggest Iran had carried out some weapons-related research.

According to November’s IAEA report, Parchin may have been the site of tests of high explosives that could be used to detonate a nuclear bomb — experiments the agency called “strong indicators of possible weapon development.”

“It is disappointing that Iran did not accept our request to visit Parchin during the first or second meetings,” IAEA Director General Yukiya Amano said in the IAEA statement. “We engaged in a constructive spirit, but no agreement was reached.”

The November report states that Iran built a large, cylindrical chamber at Parchin in 2000 that was designed to contain the force of up to 70 kilograms (154 pounds) of high explosives. IAEA inspectors visited the site twice in 2005, but did not go to the building now believed to have housed the test chamber, the report states.

“It remains for Iran to explain the rationale behind these activities,” the report noted.

The talks come as Iran is under intense pressure to demonstrate that it has no intention of pursuing nuclear weapons. U.S. and European sanctions are crippling its currency, while a new round of sanctions are targeting its crude oil sales, which make up about half of Tehran’s revenue.

In the meantime, Israel is making clear it is pondering an attack on Iran’s nuclear infrastructure. Israel is widely believed to have nuclear weapons itself, though it has never declared itself a nuclear power and considers Iran an existential threat.

Iran has threatened to cut off the Strait of Hormuz, the only shipping lane out of the oil-rich Persian Gulf, if it is attacked. But last week, it also proposed a resumption of long-stalled talks with European powers and Security Council permanent members aimed at resolving the issue.

Sanaa, Yemen (CNN) — Hundreds of voters flowed into Sanaa’s old town section Tuesday to cast ballots to replace Yemen’s longtime ruler, Ali Abdullah Saleh.

While the election is short on candidates — only Vice President Abdurabu Mansur Hadi, who took over when Saleh stepped down in November after months of protests, is on the ballot — it appeared to be long on hope.

“It’s the first time people in Yemen are electing somebody on their own, without being influenced by political parties,” said Mohammed al-Rowdy, a voter who works with the Interior Ministry. “This is a people’s election. That’s why we are optimistic things will get better.”

Officials in Sanaa described a successful effort Tuesday, but conditions in the southern port city of Aden were different. Four people were killed in clashes between gunmen and security forces, according to two senior security officials in the city.

Another 14 people were injured and were being treated at a hospital, security officials said.

Some gunfire was heard in several districts in Aden.

But there were no signs of such problems at a voting site in Sanaa, the At Altabari school — one of the oldest in the capital — as voters of all ages streamed in.

They left with ink on their fingers and thumbs, proof of their participation in a historic election that signifies the formal end of Saleh’s 33-year reign.

European observers said early turnout was healthier than expected.

“I was particularly very impressed in seeing the women turning out,” said Michele Cervone d’Urso, European Union ambassador to Yemen, who was observing the polling station. “The women are the key for this county, for sedating this country,” he said in reference to the need to calm conditions there. “They have to be recognized as a key part of society.”

Security around Sanaa and elsewhere was tight Tuesday.

Around the capital, posters of Hadi has replaced images of Saleh.

“A New President for a New Yemen,” read a large banner hanging from Change Square, which had been the epicenter of the anti-government movement last year.

Some who took part in the protests said they were not particularly excited about Tuesday’s vote.

“Maybe you can call them elections,” Nadia Abdullah said. “But for me, elections should have more than one candidate.”

Abdullah said she would stand by Hadi as long as he made good on his promises.

“If he goes through with it, we will stand hand in hand with him,” she said. “If he doesn’t, or if we see a lot of game-playing between him and the government, I believe the youth will remain in the squares. They would say, ‘Leave,’ as they did to Ali Abdullah Saleh.”

Abullah al-Saidi, 27, an accountant who volunteered as an election observer, told CNN he voted against Hadi by putting an “X” next to the name instead of a check. He said he believes many people do not realize they have the option of voting against the vice president.

“He is old school — I don’t believe he will change a lot,” al-Saidi said of Hadi.

D’Urso said the elections are not “simply for vice president Hadi. These are the elections for process, a different Yemen. And you can see Yemenis want to move to a different type of society, one of co-existence and tolerance. It’s not going to be easy. I think transition in this country will probably take a generation, but I think we are moving forward, and we have kicked off in the right way today, at least here in Sanaa.”

Human Rights Watch called on Hadi to make clear changes right away.

“Yemen’s potentially historic transition will be off to shaky start unless Hadi makes an immediate break with the abuses of the past,” said Letta Tayler, Yemen researcher for the organization. “Yemen’s new leader needs to move decisively to usher in promised reforms that uphold human rights and the rule of law.”

The 65-year-old Hadi is a British-, Egyptian- and Soviet-trained army officer, recently promoted to the rank of field marshal. He has been vice president since 1994 and is running for a two-year term as president on pledges of improving security and creating more jobs.

But he’s never had much of a power base of his own, and Yemen’s problems will take much longer to fix than the two-year mandate he’s expected to receive. It’s the poorest country in the Middle East, with a severe shortage of water and rising levels of malnutrition among its population of about 25 million.

Even before last year’s upheaval, Saleh faced a separatist movement in the south, sectarian tensions in its north and the growing presence of what Western officials describe as al Qaeda’s most dangerous affiliate, al Qaeda in the Arabian Peninsula.

For some, particularly in the once-independent south, Hadi is too closely tied to Saleh’s rule to represent any change.

“Why do people expect southerners to celebrate that Saleh is gone?” said Mohammed Mosed Okla, a prominent separatist leader in Aden. “His regime is still in control, and his family still controls all the major security factions in the country. We will not be tricked again, and southerners will not celebrate until complete change takes place in south Yemen.”

Hussein al-Aqil, a professor at Aden University and another separatist leader, said Hadi watched as Saleh “oppressed us for more than two decades.”

“I was imprisoned for three years because I expressed my opinion and rejected the corruption that Ali Saleh stood behind,” al-Aqil said. “The old regime tortured me and made me suffer for years. Hadi is part of the old regime and will not be recognized as a southern leader.”

Ahead of the vote, officials set up at least 10 new checkpoints in Aden. But only hours before polls opened, explosions rocked four separate neighborhoods late Monday. Security officials said no one was hurt.

Saleh handed over power to Hadi as part of a deal brokered by Persian Gulf states and will formally relinquish his office after Tuesday’s vote. He is in the United States, officially for medical treatment for wounds suffered in a June assassination attempt at his presidential palace during street battles between government troops and tribal fighters.

The United States has been backing Yemeni efforts against al Qaeda and has periodically struck targets inside Yemen, as in the September drone strike that killed American-born cleric Anwar al-Awlaki.

Gerald Feierstein, U.S. ambassador to Yemen, said the transition laid out in the Gulf plan as well as efforts to boost the economy and deliver basic services will be critical “in terms of our ability to defeat al Qaeda and other violent extremist organizations in the country.”

“All of these elements are going to help us defeat al Qaeda and eliminate them as a threat here in Yemen, to the region and to the world,” Feierstein said.
