A roadside bomb has ripped through an armoured car, killing two local politicians and badly wounding a third in a disputed town north of Baghdad, officials said. The explosion struck on Tuesday just north of the town of Tuz Khurmatu, 175km from the capital, and also killed one of the group’s bodyguards and wounded another, according to a police colonel and a medic at the local hospital. Town mayor Shallal Abdul, city council chief Abdulqader Naimi and Salaheddin provincial councillor Rashid Khorshid had been travelling together to inspect a road paving project north of Tuz when the bomb went off. Naimi and Khorshid, both candidates in provincial elections due to be held on April 20, were killed, and Abdul was badly wounded and transported to a hospital in the Kurdish city of Sulaimaniyah.
