The toll from a series of explosions that rocked Baghdad Thursday rose to 57 killed and 179 others wounded, Iraq's health ministry spokesman said.

A row of blasts and a suicide bomber hit mainly Shi'ite areas in the first major attack on Baghdad since a crisis erupted between its Shi'ite-led government and Sunni rivals just days after the last U.S. troops withdrew.
