Afghan deputy mayor slain while praying

KABUL, Apr 20 (AP): Insurgents killed a vice mayor of the southern city of Kandahar while he was praying at a mosque, an official said Tuesday, the latest brazen attack on government officials in the volatile region where troops are preparing for an assault on Taliban forces.
Meanwhile, NATO said one of its convoys in Khost province, on the border with Pakistan, fired on a vehicle that ignored warnings to stop late Monday night, killing four people inside the car.
