LONDON (AP) — A former member of the Syrian military was charged in Britain with three counts of murder as a crime against humanity for attacks on civilians in Damascus in 2011, British prosecutors said Monday.

The Crown Prosecution Services said it marks the first time they have brought those charges in the U.K. under the International Criminal Court Act of 2001.

The 58-year-old who was a member of the Syrian Air Force Intelligence department also faces three counts of torture and one count of conduct ancillary to murder. He is due to appear Tuesday in Westminster Magistrates’ Court.

“The charges are extremely serious and show that we fully support the U.K.’s ‘no safe haven’ policy in relation (to) alleged war criminals,” Metropolitan Police Cmdr. Commander Helen Flanagan said. “Where we are presented with allegations of war crimes and crimes against humanity that fall within our jurisdiction, then, as we have shown here, we will not hesitate to investigate those rigorously and robustly.”

The man, who now lives in the U.K., was part of a group that was assigned to suppress demonstrations in the Damascus suburbs, prosecutors said. Two of the killings occurred on April 22, 2011 and one in June 2011, according to the charges.

Authorities have not named the defendant because his lawyer is seeking a court order to protect his identity.

British prosecutors can charge offenders with some international offenses, including crimes against humanity and torture, even if they were committed outside the country.
