Officials in Iraq say at least three suicide bombers struck a state-run power plant on September 2, killing seven people and injuring several others in an attack claimed by the extremist Islamic State (IS) group.
The attack was carried out in the Iraqi city of Samarra, around 125 kilometers north of the capital, officials said.
Iraqi Electricity Ministry spokesman Musaab al-Mudaris said seven of the plant's employees were killed and eight security officers wounded, though there were conflicting accounts of the number of injured.
Mudaris said there were four attackers, one of whom was shot dead, the Associated Press reported. The others blew themselves up, the AP quoted him as saying.
At least one of the attackers was disguised in a security-forces uniform, according to officials.
IS militants later on September 2 claimed responsibility for the attack, which began at around 3 a.m.
IS captured large swathes of Iraq in 2014 but now controls just two pockets of territory there.
