Thousands of Cambodian workers have fled Thailand since the military coup in Bangkok, and more people are crossing the border every day. Workers are crossing over mostly via the border town of Poipet in Banteay Meanchey province. Cambodian officials say some have been forced out while others are fleeing. The government officials put the number of workers who have left the country at 20,000, but human rights groups say the number could be double that. Cambodian authorities are working with the International Organization for Migration to help workers once they get across the border.Bangkok has also been cracking down on migrant workers from Myanmar. Workers say Thai security forces have shut down illegal crossing points along that border, stranding many who cross back and forth for work.
