A Lesotho official says police have been told to abandon their posts and not wear uniforms to avoid being targeted in attacks during the country's continuing power vacuum.

Assistant Police Commissioner Lehloka Maphatsoe said Tuesday he heard reports of an alleged attack on a police training school late Monday.

At least one policeman was killed when the military disarmed police stations on Saturday. Radios were jammed in what the prime minister said was a coup attempt in the country of 2 million people.

Prime Minister Thomas Thabane fled to South Africa, where he has been meeting with regional leaders. It is unclear when he will return to Lesotho.

Southern Africa's 15-nation regional body says it will urgently send an envoy and observers to Lesotho to help restore stability and security.
