SITTWE - Tens of thousands of displaced Muslim Rohingyas and ethnic Rakhine Buddhists were in need of food, water and shelter in northwestern Myanmar on Thursday after fleeing the country's worst sectarian clashes in years. Houses were burnt down late on Wednesday in two villages near the Bangladesh border, but there were no reports of further deaths. Scores of people are feared to have been killed in the rioting that broke out in Rakhine state on June 8. Places that were flashpoints earlier in the week, including the state capital Sittwe, were quiet as violence started to subside after days of arson attacks and killings that have presented reformist President Thein Sein with one of his biggest challenges since taking office last year. The violence had killed 29 people as of Thursday and displaced more than 30,000, said Htein Lin, secretary of the Ministry for Border Affairs. Around 2,500 houses have been burnt down. "Tensions between the two groups have eased. There are around 20,000 refugees in Sittwe. Most of them are from the villages where people fled in fear of the violence," Aung Myat Kyaw, a senator for Rakhine state, told Reuters. "They are in need of food and, because of the heavy rain, there are concerns about the refugees' health and whether they have enough shelter," he added. The army has taken hundreds of Rohingyas to Muslim villages outside Sittwe to ensure their safety. "They are worried for their lives. The army is there so their life is secure," said Shwe Maung, a Muslim member of parliament for the ruling Union Solidarity and Development Party. "There are still so many Rohingyas in downtown Sittwe and they are afraid of being attacked." The United Nations and a medical aid group said this week they were pulling staff out of the area because of the violence. U.N. special envoy for Myanmar, Vijay Nambiar, travelled to the area on Wednesday.
