In Iraq, at least 20 people were killed and more than 80 wounded in a series of weekend explosions in Baghdad. In the deadliest incident, eight Iraqi police officers were killed when a suicide bomber detonated explosives at the scene of a prior attack. Two U.S. soldiers were killed and three were wounded when a bomb hit a U.S. military patrol just miles from the expansive base known as Camp Victory. Violence in Baghdad has escalated in recent weeks as Iraqi lawmakers debate whether to request an extended U.S. occupation beyond the withdrawal date for later this year.
