Libya will return to Egypt on Monday the bodies of 20 Egyptian Christians killed in 2015 by Islamic State in its former Libyan stronghold of Sirte, a Libyan security official said.

The bodies were recovered in October after the area where they were buried was recaptured from the jihadist group.

The Coptic Christians were beheaded on a beach in February 2015 wearing orange jumpsuits, according to a video posted by Islamic State.

Their bodies will be flown from the western city of Misrata to Egypt, a Libyan official said, adding that one victim was from Ghana.

Islamic State took control of Sirte in 2015 and lost the city late last year to local forces backed by U.S. air strikes.
