Militants have launched a suicide attack on a natural gas plant near the Iraqi capital Baghdad, killing at least 11 people and injuring a dozen more.
Six people then entered the site with explosive vests and fought security officers, the Reuters news agency reported. Three gas storage tanks were set on fire during the fighting.
Flames and smoke could be seen billowing from the facility.
More than 100 people have been killed in terrorist attacks over the last week, mostly in a car bomb blast that claimed the lives of 93 people in a market in the Shia Muslim area of Baghdad. Shia Muslims are considered apostates by extremist Sunni groups, like Isis.
The market attack was followed by two car bombs at checkpoints and then a few hours later by a twin suicide bombing attack on a police station
Isis has not only focused on Baghdad, with militants attacking a cafe in the northern city of Balad on Thursday. Thirteen Real Madrid fans who were watching a football game at the time were killed .
The attacks come amid a political crisis in the country over changes to the way the government operates.
Baghdadi businessman Hussein Abdullah told the AFP news agency: “Politicians are fighting each other in parliament and government while the people are being killed every day.”
