(TAP) - At least 22 people, including three Buddhist monks, were shot dead at close range in central Myanmar last week, according to a doctor's post-mortem report, in what opponents of military rule say was a massacre of civilians conducted by the army.

A spokesman for Myanmar's junta, which staged a coup two years ago to depose the elected government, said its troops had been involved in clashes with rebel fighters in the Pinlaung region of southern Shan state but had not harmed any civilians.

Junta spokesman Zaw Min Tun said in a statement the Karenni Nationalities Defense Force (KNDF) and another rebel group entered the village of Nan Neint after government forces arrived to provide security with a local people's militia.

"When the terrorist groups violently opened fire… some villagers were killed and injured," he said.

A spokesman for the KNDF said its soldiers entered Nan Neint on Sunday and found dead bodies scattered at a Buddhist monastery.

Fighting has been raging in the area for at least two weeks, with about 100 structures burnt down in and around the site of the alleged massacre in Nan Neint, according to local media reports, resistance forces and satellite images verified by Myanmar Witness, an organisation that documents human rights violations.
