At least 27 people were killed when a bomber detonated his explosive vest at a funeral for the relative of a Shiite Muslim militia commander in the eastern Iraqi province of Diyala on Monday, security and medical sources said.
The attack in Muqdadiya, 80 km (50 miles) northeast of Baghdad follows the deadliest bombing inside the capital so far this year, which left 78 people dead in a Shiite district on Sunday.
Security officials and police in Diyala said the target of the attack was two local commanders of the Hashid Shaabi umbrella group of Shiite militias who were attending the funeral ceremony for one of their relatives.
“The suicide attacker approached the local Hashid commanders and then blew his vest up, killing both with many others,” said one police major on condition of anonymity. A further 55 people were wounded, the sources said.
There was no immediate claim of responsibility for the bombing, but attacks on Shiite Muslims are often claimed by ISIS militants who control large parts of north and western Iraq.
Iraqi officials declared victory over the insurgents in Diyala a year ago, but ISIS has remained active. The Badr Organization has established itself as the ascendant militia in the region after rolling back the insurgents.
Security officials and witnesses say the situation inside Muqdadiya is very tense, with dozens of Shiite militia members deployed in the streets with no presence of the security forces.
Militia elements have been accused of attacking Sunni mosques and residents in Diyala following similar bombings in January, but the groups have denied the allegations and blamed ISIS.
