BAGHDAD (AP) — In the deadliest violence in Baghdad this year, three car bombs claimed by the Islamic State group killed 93 people across the Iraqi capital Wednesday, demonstrating the extremists’ ability to mount significant attacks despite major battlefield losses.

The separate bombings, which also wounded 165 people, came at a time of turmoil and deadlock in Iraq’s government and parliament. The Interior Ministry blamed the attacks on “political bickering” that is increasingly threatening the security of the civilian population.

The largest car bomb ripped through a crowded outdoor market selling food, clothing and household goods in the predominantly Shiite neighborhood of Sadr City during the morning, killing at least 63 people and wounding 85.
