A protest over the burning of Qurans at a U.S. base turned violent Sunday, leaving a protester dead and several U.S. service members and police wounded, officials said.  The violence in northern Kunduz province came a day after a gunman killed two U.S. military officers inside the highly secured Afghanistan Ministry of Interior.  The demonstration Sunday -- the sixth day of protests -- began peacefully, said Kunduz police spokesman Sayed Sarwar Hussaini.  But it soon turned violent as demonstrators attacked the police chief's office and a U.S. military site.  Protesters threw a hand grenade at the base, injuring seven U.S. military personnel believed to be Special Forces members, Hussaini said.

The man who shot two military officers Saturday at the interior ministry was a junior intelligence officer with ties to a Pakistani religious school, an Afghan counter-terrorism official said.  The gunman was identified as Abdul Saboor, an employee in the ministry's intelligence department, according to the official, who spoke on condition of anonymity because he was not authorized to release the information.
