The Britain-based Syrian Observatory for Human Rights said IS fighters seized Ein Issa and nearby areas before noon yesterday.
The fall of the town described as being “liberated” on IS-associated outlets comes after the main Kurdish militia known as the People’s Protection Units, or YPG, captured wide areas in northern Syrian from the extremists, including the border town of Tal Abyad, once a main point for IS trade and smuggling in of foreign fighters.
In another push, IS fighters last month attacked the northern Syrian town of Kobani, killing more than 200 people in the town that became a symbol of Kurdish resistance against extremists. Fighting continued for days until IS militants were killed or surrendered.
Earlier on Monday, the Islamic State released a new video purporting to show the killing of two Syrian men in the militants’ stronghold of Raqqa, allegedly for spying on the group. IS has killed hundreds of people since it declared an Islamic caliphate in June last year with the city of Raqqa as its de facto capital.
