A series of insurgent attacks across Iraq killed at least 30 people Saturday, including a number of police recruits. A suicide bomber blew himself up outside a police recruiting station in central Baghdad, killing at least 16 people. Al-Qaida in Iraq claimed responsibility in an Internet posting, although the statement's authenticity could not be confirmed. Two separate suicide bomb attacks in a city south of Baghdad -- one at a police checkpoint and a second attack targeting civilians -- left another 10 people dead. A bomb hidden in a vegetable cart exploded south of Baghdad as the funeral procession for a slain top Shi'ite cleric passed close by, killing two people. No one in the funeral party was injured. Gunmen and roadside bombs also targeted police officials and Iraqi soldiers in separate attacks elsewhere in Iraq.
