Muslim Rohingyas under vicious attack in Myanmar: rights group SITTWE, Myanmar (Reuters) - A human rights group expressed concern for the safety of thousands of Muslims on Saturday after revealing satellite images of a once-thriving coastal community reduced to ashes during a week of violence in western Myanmar. The images released by the New York-based Human Rights Watch show "near total destruction" of a predominantly Rohingya Muslim part of Kyaukpyu, one of several areas in Rakhine state where battles between Rohingyas and ethnic Rakhine Buddhists threaten to derail the former Burma's fragile democratic transition. More than 811 buildings and houseboats were razed in Kyaukpyu on October 24, forcing many Rohingya to flee north by sea toward the state capital Sittwe, said Human Rights Watch. "Burma's government urgently needs to provide security for the Rohingya in Arakan (Rakhine) State, who are under vicious attack," said Phil Robertson, the group's deputy Asia director.

Dozens of boats full of Rohingyas with no food or water had fled Kyaukpyu, an industrial zone important to China, and other recent hotspots were seeking access on Friday to overcrowded refugee camps around the state capital Sittwe, according to four Rohingya refugee sources. Some boats were blocked by security forces from reaching the shore and few Rohingyas managed to reach the camps, the sources said by telephone. Wan-lark foundation, an organization that has been assisting Rakhine Buddhist refugees, said no clashes in the state had been reported to them since Friday night, but dead bodies of Rakhines had been found. Around 6pm last night in Kyawtyaw, the bodies of 16 Rakhines were found in the sea. They had died during the attacks on Thursday. We're looking for more bodies," representative Tun Mein Thein said on Saturday. The chaos suggests the reformist government is struggling to contain historic ethnic and religious tensions suppressed during nearly a half century of military rule that ended last year. A Rakhine government spokesman put the death toll at 112 as of Friday. But within hours state media revised it to 67 killed from October 21 to 25, with 95 wounded and nearly 3,000 houses destroyed. The death toll could be far higher, said Human Rights Watch, citing "allegations from witnesses fleeing scenes of carnage and the government's well-documented history of underestimating figures that might lead to criticism of the state." The clashes come just five months after communal unrest killed more than 80 people and displaced at least 75,000 in the same region. A boat carrying 120 Muslims from Kyaukpyu was intercepted by Rakhines, who killed the men and raped the women, the advocacy group Burmese Rohingya Organisation UK said in a statement. This claim could not be verified. "Ethnic cleansing is happening under the noses of the international community and they are doing nothing," said Tun Khin, the group's president. We have confirmed reports that hundreds of people have been killed and the government must be aware of that. Kyaukpyu is crucial to China's most strategic investment in Myanmar: twin pipelines that will carry oil and natural gas through the town on the Bay of Bengal to China's energy-hungry western provinces. The United Nations has warned that Myanmar's fledgling democracy could be "irreparably damaged" by the violence. Buddhist-majority Myanmar's government regards the estimated 800,000 Rohingyas in the country as illegal immigrants from Bangladesh, and not as one of the country's 135 official ethnic groups, and denies them citizenship. But many of those expelled from Kyaukpyu are not Rohingya but Muslims from the officially recognized Kaman minority, said Chris Lewa, director of the Rohingya advocacy group, Arakan Project. "It's not just anti-Rohingya violence anymore, it's anti-Muslim," she said. Reporting by Reuters staff reporters; Writing by Andrew R.C. Marshall; Editing by Jonathan Thatcher
