At least 11 people were killed in a bomb attack against a state-run cooking gas factory in Baghdad's northern outskirts.
A suicide car bomb went off at the entrance of the facility in Taji at around 4am Irish time, allowing another vehicle carrying at least six attackers with explosive vests to enter the facility where they clashed with security forces.
A spokesman for Baghdad Operations Command said three of the facility's gas storages were set alight amid the violence before security forces were able to bring the situation under control.
There was no immediate claim of responsibility for the attack, but so-called Islamic State militants controlling vast swathes of the country's north and west have conducted bombings this week that killed around 100 people.
Prime Minister Haider al-Abadi said the militants were taking advantage of a political crisis in the country, sparked by his attempt to overhaul its quota-based governing system, to conduct bombings in areas under nominal government control.
A US-led coalition backing the Iraqi government in its fight against Islamic State has been training army forces for months at a military base located in Taji.
