Baghdad - A suicide car bomb explosion ripped through a police checkpoint in Baghdad on Tuesday, killing 23 people and wounding more than 40, police and medical sources said.
The suicide bomber detonated an explosives-laden vehicle at an entrance to the northwestern neighbourhood of Kadhimiyah, a police colonel and an interior ministry official said.
At least five of the those killed were policemen, as were eight of those wounded, said police and medical sources, who both gave figures higher than 40 for the number of wounded.
The predominantly Shiite neighbourhood of Kadhimiyah lies across the Tigris river from the mainly Sunni district of Adhamiyah and is frequently targeted when sectarian tension in the country is high.
The neighbourhood, which is home to one of the holiest Shiite shrines, is named after Musa Kadhim, the seventh of 12 revered imams in that branch of Islam.
