Two gunmen shot a Muslim cleric to death inside a mosque in southern Afghanistan, the second such incident in the area in less than two weeks, an official said Tuesday. The two men drove up to the mosque in Kandahar city on a motorcycle Monday night, shot the cleric, then drove off, said Zulmai Hayubi, a spokesman for provincial Gov. Tooryalai Wesa. The attackers have not been identified. The killing follows a similar attack a little more than a week ago in which the head of one of Kandahar's main mosques was shot to death by gunmen while sitting inside the mosque. Hayubi said both incidents were under investigation, and it was unclear if the attackers were Taliban or people angered or insulted by the clerics in some way.
