A court in Germany will begin hearing a case Wednesday against a Syrian doctor accused of crimes against humanity of torturing and killing inmates at a government-run prison in his home country.

Federal prosecutors say the doctor, identified as Alaa M. in keeping with German privacy rules, worked at a military intelligence prison in the Syrian city of Homs from April 2011 until later 2012.

Alla is accused of killing one person, torture in 18 cases, causing severe physical and psychological harm to another person, and other crimes, including one that led to another death.

The defendant entered Germany in 2015, and German authorities permitted him to practice medicine after recertifying his Syrian medical credentials. He worked at a clinic near Kassel in central Germany, where multiple Syrians recognized the doctor from his time in Syria and reported him to German Police.

In one case, he was accused of beating an anti-government demonstrator after prison officials called the doctor to the hospital to treat a man experiencing an epileptic attack following torture. That man later died.

Similarly, in another case, German authorities accused the doctor of intentionally killing a prisoner via injection to demonstrate "his power and at the same time to suppress the uprising of a part of the Syrian Population," the Frankfurt regional court said.

The defendant has denied all the allegations.

The latest case follows last week's landmark conviction of a former senior member of the Syrian secret police for crimes against humanity, including the torture of at least 30 anti-government demonstrators at a detention center in Douma, Syria.

Alaa M. has been in pretrial detention since his first arrest in June 2020.
