The remains of 20 Egyptian Christians, who were executed in 2015 by the Islamic State (IS) militant group in Libya, arrived in Egypt on Monday, official MENA news agency reported.

Egypt's Coptic Pope Tawadros II, along with security officials, received the remains at Cairo International Airport, MENA said.

Official Ahram Online reported that the remains will be identified through DNA samples taken from the victims' families.

In February 2015, the IS published a video showing the beheading of 21 Egyptian Coptic Christians abducted in the Libyan city of Sirte.

Libyan security forces discovered the bodies in October last year after the city was recaptured from IS militants.
