A suicide bomber detonated a pickup truck loaded with explosives, killing 32 people at a marketplace in a contested town claimed by Baghdad and the Kurdish region, Iraqi officials say. The powerful explosion Tuesday evening in Tuz Khormato injured at least 75 people, AP reports. Tuz Khormato is about 210km (130 miles) north of Baghdad. The town has long been the scene of skirmishes between Kurdish Peshmerga fighters and the mostly Shiite militia forces loyal to Baghdad.
