Suspected Islamic State fighters stormed an Iranian-run power plant and police stations in the Iraqi oil city of Kirkuk on Friday in an apparent counter-attack as Iraqi forces advanced on militant-held Mosul about 100 miles to the northwest.Iraqi media said at least 13 workers, including four Iranians, were killed in the pre-dawn assault by suicide bombers armed with rifles and that a curfew was imposed on the city claimed by both Iraq's government and the country’s autonomous Kurdish region.
