The number of police killed in the clash Sunday in Panjwayi district of Kandahar province rose to five as a wounded officer died in hospital, said provincial spokesman Dawood Ahmadi.
One of the two dead Taliban commanders was identified as Mullah Abdul Manan, who Ahmadi claimed led a Taliban suicide squad responsible for numerous bombings. This could not be immediately confirmed.
An unknown number of civilians were also wounded in the fighting, which erupted after security forces surrounded a village where the insurgents were hiding, the spokesman said. Up to 100 rebels are believed to have fled after the battle, he said.
