Cambodia has informed the UN Security Council that Thai forces have violated its territory near an ancient World Heritage Site temple where hundreds of troops continued to face off Sunday. Cambodia's permanent mission in New York submitted a letter to the chairman of the Security Council and the chairman of the General Assembly to "draw their attention to the current situation on the Cambodian-Thai border," Information Minister Khieu Kanharith said. "Cambodia is not asking for UN intervention. We still stick to Prime Minister Hun Sen's instructions to try to solve the problem peacefully between the two sides," the minister told reporters in the Cambodian capital, Phnom Penh. The conflict over territory surrounding Preah Vihear temple escalated when UNESCO recently approved Cambodia's application to have the complex named a World Heritage Site. Thai activists fear the new status will undermine Thailand's claim to nearby land since the border has never been demarcated.
