"Two men asked police to let them spend the night in their post. The police accepted and gave them food," Jawed Faisal, spokesman for the Kandahar provincial governor, told AFP.
"After dinner, the men grabbed the guns of the policemen and shot dead seven police and wounded one and fled."Taliban insurgents have been busy bees the past few days in what is termed a "spring offensive"- they've killed at least 14 Afghan policemen and soldiers.
The search is on to find the two men, who are more than likely back with the Taliban.

Why anyone thinks the Taliban are willing to negotiate is beyond me. They will take over again, once foreign troops are out of there.
