December has got off to a bloody start in Iraq, with more than 30 people killed today. Baghdad’s police academy was targeted by twin blasts. People were queuing up to enrol when a car bomb exploded. A suicide attacker also blew himself up. Earlier in the city, a roadside bomb wounded a senior Iraqi military officer and killed up to three other people. In Mosul, a suicide car bomber claimed at least 14 lives. Violence has fallen sharply over the last year but it did rise in November.
