NBC, msnbc.com and news services from KABUL, Afghanistan — At least 11 people were wounded Wednesday when shots were fired as violent protests erupted for a second day after Muslim holy books were burned at NATO's main base in Afghanistan.

The shots were fired into demonstrators when they charged at police lines and smashed car windows, witnesses told Reuters. It appeared police had fired the shots but there was no immediate confirmation from Afghan security forces.

On Tuesday thousands of demonstrators besieged the Bagram air base in protest at the alleged burning of copies of the Quran.
