BAGHDAD - Suicide bombers attacked two Shia processions in Baghdad on Monday, killing at least 11 people and wounding more than 40, police and medical sources said.

A bomber detonated his explosive vest in the middle of one Shia procession in the Amil district of southern Baghdad, killing six and wounding 25, the sources said. In the deadliest attack, a bomber targeted a market in the Amil neighbourhood of southern Baghdad, killing at least six people and wounding 16 or more.

Another bomber detonated explosives near a garage for taxis and buses and a tent providing refreshments to passersby as part of a Shia religious ritual, killing at least four people and wounding 18. There was no immediate claim of responsibility for the attacks, but the Islamic State militant group frequently targets members of Iraq’s Shia majority, whom it considers heretics.

IS overran large areas north and west of Baghdad in 2014, and while the militants have since lost signficant ground, they retain the capacity to carry out frequent attacks in government-held areas.
