On June 5, 2006, 231 Hmong refugees fleeing Laos were detained by police in Amphoe Khao Kho, Phetchabun Province for illegal entry into Thailand. The Hmong were seeking asylum at the province's Ban Huay Nam Khao, where about 6,500 ethnic Hmong are being sheltered, but the Thai military refused to allow them to stay. Most of the Hmong claim they fought against the communists in the Secret War.
