A Christian Syrian in the northeastern Hasakeh province has decapitated an Islamic State (IS) militant to retaliate the deaths of Christians by the terrorist group, Al Monitor reported on Friday. The UK-based Syrian Observatory for Human Rights announced the Assyrian fighter "beheaded the IS jihadist in revenge for abuses committed by the group in the region," according to The Guardian. The Christian was fighting alongside Kurdish forces who earlier this month drove ISIS out of more than a dozen Assyrian villages in the Hasakeh province. In February, ISIS abducted at least 220 Assyrian Christians from the province of whom only 19 survived.
