Police in the northern province of Badakhshan say several hundred demonstrators ran toward a NATO compound where four attackers and five police were injured in clashes.

Protesters also burned an American flag at a mosque after Friday prayers.

In western Farah province, police said two people were injured in another protest.

Police say initial reports that someone was killed were wrong.

The Rev. Terry Jones from the Dove Outreach Center in Florida triggered outrage when he promised to burn the Qur'an on the anniversary of the Sept. 11 attacks.

He canceled the plans Thursday but then said he was reconsidering.
