The woman was accused of "hiding the actions of a terrorist group to which her husband belonged", Supreme Judicial Council spokesman Abdel Sattar Bayraqdar said, referring to IS.

"The court condemned another Syrian terrorist to life in prison for belonging to IS and for taking part in attacks against Iraqi soldiers," he said.

Iraq in December declared victory against IS after a years-long battle to retake large swathes of territory the jihadists had seized in 2014.

Several hundred foreigners, both men and women, are thought to have been detained in the fighting.

An Iraqi court last month condemned to death by hanging a German woman of Moroccan origin after finding her guilty of belonging to the jihadist group.

She is believed to be the first European woman to be sentenced to death in Iraq in relation to IS.

In September last year, Iraq sentenced to death by hanging a Russian man who was captured in second city Mosul and found guilty of fighting for the group.

In December, a Swede of Iraqi origin was among 38 people executed after being convicted of "terrorism".

Three French women awaiting trial in Baghdad could face the death penalty for joining IS, sources with knowledge their cases told AFP last month.
