BAGHDAD (AP) — A car bomb exploded in a sprawling Shiite neighborhood of Baghdad on Thursday morning, killing at least five civilians and wounding 19, officials said.

Two police officers said the blast struck a bus and taxi stop around rush hour in the eastern Sadr City neighborhood. Among the five killed was a 7-year old child. The attack also wounded 19 people, the officers added.

A medical official in a nearby hospital confirmed the causality figures. All officials spoke on condition of anonymity because they are not authorized to talk to the media.

The attack followed a wave of bombings on Wednesday that struck in mainly in Shiite neighborhoods, killing 33 people. At least seven of them died in Sadr City when a bomb in a parked car detonated at a bus stop.

The spike in violence comes amid growing tension between the Shiite-led government and Iraq's Sunni minority over what they consider second-class treatment. A bloody government crackdown on militants last month in a protest camp in the country's north fueled the tension.

No one immediately claimed responsibility for the Wednesday and Thursday attacks, but car and suicide bombings are a hallmark of al-Qaida's Iraq branch.

The spike in attacks, after a general decrease in violence, has raised fears of a return to the sectarian bloodshed that pushed the country to the brink of civil war in 2006-2007. Shiite militias have so far been largely restrained in their reactions to such bombings.
