PHNOM PENH, Cambodia (AP) — Tens of thousands of Cambodians have fled neighboring Thailand to return home, fearing a crackdown on migrant workers under Thailand’s new military government, a senior Cambodian official said Saturday. Activists said the workers had been forced out of the country, but Thailand denied the accusation.

More than 84,000 workers have returned this month through the border crossing at the western Cambodian town of Poipet, said Kor Samsarouet, the governor of Banteay Meanchey province, where Poipet is located. About 40,000 crossed over on Friday alone, and 10,000 returned to Cambodia on Saturday morning, he said.
