Move comes despite international concerns that they will face persecution in their home country
The Thai government rejects accusations by the international community that thousands of Lao Hmong refugees were being forcibly sent back to Laos. The Thai military carried out the deportation under tight security.
The deportation of 4,000 Hmong to Laos began in the early hours of Monday with convoys of military trucks and buses ferrying people to the border.
Human rights groups fear the Hmong, who have been held at the Huay Nam Khao refugee camp, will be persecuted once they return to Laos.
The U.S. government called for a suspension of the operation, saying Thailand has violated international humanitarian principles by forcibly returning the Hmong.
Thai government spokesman Panitan Wattanayagorn denies that accusation. He says Lao authorities promise to grant amnesty to those returning.
