Asharq Al-Awsat reports: A man was sentenced to life in prison by a German court on Tuesday in a landmark trial regarding crimes committed by ISIS against the Yazidi people in Iraq.

The Frankfurt Higher Regional Court found Taha Al-J, an Iraqi native whose full name was not released for legal reasons, guilty of genocide and a war crime resulting in the death of an enslaved Yazidi girl, the German News Agency (dpa) reported.

He must also pay damages of 50,000 euros (56,391 dollars) to the girl's mother.

Presiding judge Christoph Koller said it was the world's first verdict for crimes committed by ISIS against the Yazidi minority.

Al-J was found guilty of having kept and abused a Yazidi woman and her daughter as slaves between July and September 2015. To punish the 5-year-old, he tied her to a window grate in the courtyard of the property in Fallujah in sweltering heat, where the child died of thirst.

Jennifer W, Al-J's former wife, was sentenced to 10 years in prison by the Munich Higher Regional Court in October. As a witness in the trial against Al-J, she had described her former husband as violent.

Judge Koller went into detail about the ideology of ISIS and the crimes against the Yazidis, about the enslavement of Yazidi women and girls, about rapes - which had been commonplace - and about the slave trade.

Al-J had shared the ideology, aimed at the destruction of the Yazidis, the court found.

Addressing the mother of the dead girl, Koller thanked the slender, stooped woman for testifying on a total of seven trial days. All those involved in the trial had been "deeply moved" by her account, he said. "We wish that you succeed in bearing your suffering and that you find peace," he said.
