Police in Thailand have arrested more than 400 Pakistani Christian immigrants, including children. Several pastors in Bangkok said many of the Christians fled Pakistan because they were either accused of blasphemy or threatened by radical Muslims. They have sought work and refugee status, and many reportedly have interview appointments scheduled with the United Nations. Some of the Pakistani Christians are converts from Islam. Since arriving in Thailand, they've depended on churches and others for food and housing. The Thai government says they are illegal immigrants and should be deported. The Christians say they thought Thailand would provide a safe haven for them after they escaped religious persecution.
