German prosecutors say they've charged a 30-year-old man with membership in the Islamic State group, alleging that he fought with the group in Syria in 2013.

Prosecutors said Thursday that German citizen Abdelkarim El B., whose last name wasn't given in line with privacy laws, took part in fighting near Aleppo. He's alleged to have filmed on his cellphone as he and others cut the ears and nose off the corpse of an enemy fighter, and fired shots into the head.

He was arrested in February 2014 after he left Syria for Turkey. After his release nearly a year later he returned to Germany where he was arrested in February 2015.

He is charged with membership in a terrorist organization along with breaches of humanitarian and weapons laws.
