KABUL, Afghanistan — An official says two guests invited by an Afghan police commander to eat with him at his checkpoint picked up weapons after dinner and opened fire, killing him and six of his men.

Ahmad Jawed Faisal, spokesman for the governor of Kandahar province, did not say what the motive might have been for the late Monday attack in the remote district of Arghistan.

He says one officer survived and told authorities what happened.
