Isis has claimed responsibility for two bomb attacks on Coptic Christian churches in Egypt which have killed at least 36 people.

“A group that belongs to Islamic State carried out the two attacks on the churches in the cities of Tanta and Alexandria,” the group’s news agency Amaq said.

Over 100 people were wounded in the attacks.

In the first, a bomb exploded at Saint George church in the Nile Delta city of Tanta, killing at least 26 and wounding over 70.

Later, a second blast in front of a church in Alexandria killed 11 people and wounded 66, the health ministry said.

The group recently released a video vowing to step up attacks against Christians, who it describes as “infidels” empowering the West against Muslims.
