Two car bombings in central Baghdad and one in the northern city of Mosul have killed at least 21 people and wounded nearly 100 others.
The first of today's (Monday's) two blasts in the Iraqi capital killed 15 people near a recruitment office of the Iraqi National Guard, just outside an entry gate of the heavily fortified Green Zone. A second bombing in a hotel district killed at least six others.
Authorities say the blast in Mosul killed three people, including two bombers who may have prematurely triggered the blast.
Elsewhere (Monday), an Iraqi police commander was assassinated near Baquba, and a senior science ministry official was killed in Baghdad.
Meanwhile, U.S. airstrikes are continuing in insurgent-held Fallujah. U.S. officials say the latest strikes targeted two buildings believed used by insurgents.
