BAGHDAD (Reuters) - Twenty-two people were killed and 55 wounded in clashes in Baghdad, police said on Sunday, the worst eruption of violence in the capital since Shi'ite cleric Moqtada al-Sadr called his fighters off the streets a week ago.
Near the northern city of Mosul, a group of roughly 40 students were kidnapped by gunmen for several hours before Iraqi security forces freed them.
The violence in Sadr's Baghdad stronghold, the Shi'ite slum of Sadr City, follows a week of relative calm after clashes throughout the south and Shi'ite neighborhoods of the capital.
It comes only days before U.S. ambassador Ryan Crocker and U.S. commander General David Petraeus are due to deliver key testimony to the U.S. Congress on progress in Iraq.
