Thousands of ethnic Karen villagers in Myanmar are poised to cross into Thailand if, as expected, fighting intensifies between the Myanmar army and Karen insurgents, joining those who have already escaped the turmoil that followed a Feb. 1 coup.

Karen rebels and the Myanmar army have clashed near the Thai border in the weeks since Myanmar's generals ousted an elected government led by democracy champion Aung San Suu Kyi, displacing villagers on both sides of the border.

"People say the Burmese will come and shoot us, so we fled here," said Chu Wah, a Karen villager who crossed over to Thailand with his family this week from the Ee Thu Hta displacement camp in Myanmar.
