A Syrian national accused of committing crimes against humanity and war crimes during the early stages of the Syrian Civil War has been arrested in Germany, prosecutors announced Thursday.

The federal prosecutor’s office said the suspect was detained on July 26 in the northern city of Bremen. He was remanded in custody on Thursday.

Named only as Ahmad H., the suspect is accused of perpetrating the atrocity crimes of torture and enslavement between 2012 and 2015 as a local leader of pro-government “shabiha” militiamen in Damascus. The militiamen were tasked with helping crush local dissent.

The militia allegedly operated checkpoints where “people were arrested arbitrarily so that they or their family members could be extorted for money, committed to forced labor or tortured,” prosecutors said.

The alleged crimes took place within the broader context of Syria’s brutal, ongoing civil war, which was sparked by severe suppression of protests in 2011 by the government of President Bashar Assad.

The countrywide conflict that followed has been characterized by rampant atrocity crimes, including crimes against humanity and war crimes. Assad has denied all accusations of atrocity crimes.

Since the start of the conflict, more than 580,000 people have been killed, and nearly 13 million people have been displaced.

In 2015, Germany allowed hundreds of thousands of Syrian refugees to enter the country.

Since then, Germany has become a global leader in the prosecution of Syrian war criminals under the principle of universal jurisdiction, which allows courts to prosecute suspects accused of committing mass atrocity crimes anywhere in the world.
