BAGHDAD, Iraq (AP) - Suicide bombings struck Iraq on Sunday, killing at least 23 and wounding dozens more in three attacks on an army recruiting center, a police convoy and civilians, authorities said.

The attacks pushed the death count to over 1,500 people killed from violence since April 28, when Prime Minister Ibrahim al-Jaafari announced his Shiite- and Kurd-dominated government in a country under attack from an insurgency led by Iraq's Sunni Arab minority.

In the deadliest blast Sunday, a man strapped with explosives blew himself up at a west Baghdad airfield now used as a military recruiting center, police said. Early casualty reports varied, with a hospital official saying at least 16 died while a Defense Ministry employee reported up to 25 killed.

The explosion occurred just before 9 a.m. at the recruiting center, which had been hit several times before by suicide attackers. About 400 would-be recruits jammed the gate Sunday before the bomber detonated himself, police Sgt. Ali Hussein said.

Yarmouk Hospital received 16 bodies and 39 people wounded from the attack, hospital director Ihsan al-Torfy said. He didn't rule out that other victims might have been taken to other hospitals.
