ISIS claims responsibility for bombing in northern Iraq that killed seven

BAGHDAD - Islamic State said it was responsible for a suicide car bomb attack on a police checkpoint in the northern Iraqi town of Tuz Khurmatu on Saturday which left seven people dead and 17 others wounded.
The hardline Sunni militant group said in an online statement distributed by supporters that the target was "rejectionists", its term for Shi'ite Muslims.
The attack in Tuz Khurmatu, about 175 km (110 miles) north of Baghdad, threatened to exacerbate tensions between Kurdish and Shi'ite Turkmen communities in the town, which has seen deadly clashes between paramilitary forces from each group in recent weeks.
Efforts to push back Islamic State militants in northern and western Iraq have been complicated by such sectarian and ethnic rivalries.
