Blasts across Iraqi cities kill at least 22

BAGHDAD (Reuters) - At least 22 people were killed in a series of blasts in Iraqi cities on Tuesday, police and health sources said, the latest in a spate of violence ahead of next week's Arab League summit in Baghdad.

The deadliest attack was in the southern Shi'ite holy city of Kerbala, where two explosions killed at least nine people and wounded 40, the sources said.
