A Syrian Christian fighter has beheaded an Islamic State group (IS) militant to avenge people "executed" by the jihadists in northeastern Syria, a monitor said on Friday.
The Syrian Observatory for Human Rights said the incident took place on Thursday in Hasakeh province, where IS holds large areas of the countryside.
According to the monitor, the Christian fighter, a member of the minority Assyrian community, found the jihadist in the local village of Tal Shamiram.
"He took him prisoner and when he found out he was a member of IS, the Assyrian fighter beheaded him in revenge for abuses committed by the group in the region," Observatory chief Rami Abdel Rahman said.
