On January 21, a German woman of Moroccan origin was sentenced to death by hanging on charges of providing "logistical support and helping the terrorist group to carry out crimes".

The two Germans are among hundreds of foreign suspected jihadists held by Iraqi authorities, who in December announced the defeat of IS after a gruelling three-year battle.

According to media reports in Germany, the condemned woman, named Lamia K., had left Mannheim in August 2014. She was arrested by Iraqi forces during the final stages last July of the battle for the northern city of Mosul.

At least two other German women are being held in prison in Iraq, including the teenager Linda W., who had disappeared from home in the summer of 2016, shortly after converting to Islam.

The girl from Pulsnitz in Saxony, in a meeting with German journalists in Baghdad last summer, said she wanted to return to her family and regretted her actions.

In a separate case, a suspected French jihadist, who had been sentenced to seven months in prison for illegal entry, was on Monday ordered released and deported on the basis of time served.

On Sunday, a Turkish woman was sentenced to death and 11 other foreign widows who fighter husbands had been killed to life in jail for belonging to IS.
