Two more Coptic Christians have been killed in Egypt’s Sinai Peninsula.

Egyptian security officials said suspected militants were responsible, as AP reports.

This comes days after the Islamic State threatened to wipe out Christians from Egypt and following the murder of two other Copts in Sinai.

Saad Hana, 65, was reportedly shot dead, while his son, Medhat, 45, was burned alive. Their bodies were then dumped on a roadside.

This took place in the city of El-Arish, where last week a Coptic teacher was shot dead on his way to school, four days after a Coptic vet was murdered. The BBC reports a total of six deaths in the region in the past two weeks.

All the murders have been linked to a regional offshoot of the Islamic State, formerly known as Ansar Beit al-Maqdis.

Residents of North Sinai’s cities are increasingly frequently subjected to kidnappings and killings by jihadists affiliated to the group, which pledged allegiance to Islamic State in 2014. Two Coptic priests were among those murdered in El-Arish in recent years.

The killings in Sinai follow a spate of killings of Copts elsewhere in Egypt in January, when five Copts were killed in less than two weeks.

Each had their throat cut, while money and other valuables were left behind – even though police had said robbery was the motive behind at least one of the murders.
