A Syrian Christian fighter has reportedly beheaded an Isis member as revenge for the group's violence against the region's Christians.

The Christian, a member of the minority Assyrian community, was a fighter with the Syriac Military Council, according to the London-based Syrian Observatory for Human Rights.

The incident occurred near the town of Tal Tamer in in northwest Syria.

According to the Observatory's website the beheading was carried out with a "sharp tool".

Isis has captured large swathes of land in Syria and Iraq. The group has carried out public beheadings and mass executions of hundreds of people, both Chrisitans and Muslims.

Earlier in the month Yazidi officials in Iraq reported that Isis militants had killed 300 Yazidi captives in the Tal Afar district near the Iraqi city of Mosul.
