Bomb attacks against a state-run cooking gas factory in Baghdad's northern outskirts have killed at least 11 people, including policemen, and wounded 21 others.
A suicide car bomb went off at the entrance of the facility in Taji at 1300 AEST, allowing at least six attackers wearing explosive vests to enter the facility where they clashed with security forces, police sources said.
A spokesman for Baghdad Operations Command said three of the facility's gas storages were set alight amid the violence.
A factory employee who lives nearby said after hearing a powerful blast he saw flames and black smoke coming from inside the factory.
Dozens of police and army vehicles rushed to the facility where shooting lasted for about an hour, he said.

There was no immediate claim of responsibility for the attack, but 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 on Saturday 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 IS has been training army forces for months at a military base located in Taji.
