Officials said a protester was killed when police fired during a riot after prayers in the northwestern town of Qala-e-Naw and another died from a gunshot wound in Gardez, near the Pakistani border.
Protests erupted Tuesday in the eastern city of Jalalabad, and the killing of four rioters by police further enflamed passions. Demonstrations -- many of them violent -- have occurred in at least 12 Afghan towns and cities.
Saudi Arabia joined fellow US ally Pakistan in registering dismay over the allegations, as did the 57-nation Organization of the Islamic Conference and Egypt's Muslim Brotherhood, a banned militant religious movement.
But aside from Afghans, few in Muslim lands have taken to the streets.
