Several global oil firms have urged their staff to vacate Iraq following the militant attacks in the north of the country, with concerns that they may spread to the south.

Iraq’s biggest oil refinery, Baiji, has been targeted by Sunni militants, who used machine-gun fire and mortars to attack the facility.
The plant, located to the north of Baghdad, has been closed and the facility is currently under the control of military.
