Police say two roadside bombs have exploded in the majority-Shi'ite Muslim city of Hillah in southern Iraq, killing at least 16 people.
Dozens of others were injured in the blasts.
The attacks came during the holy month of Ashura, when Iraq's majority Shi'a commemorate the seventh-century death of Imam Hussein.
Shi'ite Muslims in Iraq are often targeted by Al-Qaeda-linked militants and Sunni Muslim insurgents during Ashura commemorations.
