BAGHDAD (AP) — A series of bombings, including three over a span of less than 10 minutes, killed at least 24 people across Baghdad today, shaking the fragile sense of security the capital has maintained despite the Sunni militant offensive raging across northern and western Iraq.

The attacks are among the most significant in Baghdad since insurgents led by the Islamic State extremist group captured Iraq’s second-largest city Mosul last month. After Mosul’s fall, the government moved aggressively to try to secure Baghdad and the city has seen few major attacks in recent weeks.

Saturday’s deadliest bombing took place in the Shiite neighborhood of Abu Dashir, where a suicide attacker rammed a car packed with explosives into a checkpoint, killing at least nine people and wounding 19. Officials say four policemen are among the dead.

Later in the day, three car bombs in different neighborhoods of Baghdad went off in less than 10 minutes, killing at least 15 people.
