BAGHDAD (AFP) – A car bomb in a majority Shiite area of Iraq’s capital killed four people Saturday, officials said, the latest in a spate of attacks sparking fears of a revival of all-out sectarian bloodshed.

The explosion near a clinic in Al-Amin district of southeast Baghdad also wounded 20 people including four children.

Sunni Muslim insurgents in Iraq, including members of Al-Qaeda, consider the country’s Shiite majority to be apostates and regularly single them out for attack.

Another car bomb on Saturday, this one detonated by a suicide attacker, near a military base in the main northern city of Mosul wounded 21 people — 12 soldiers and nine civilians — according to officials.

Saturday’s violence comes as Iraq experiences one of its deadliest periods in weeks. The United Nations said more than 1,000 people were killed in May alone, making it Iraq’s deadliest month since 2008.
