The Islamic State (IS) extremist group has regained control of the northern Syrian town of Ein Issa that was captured by Kurdish fighters two weeks ago, a monitoring group said.
The Syrian Observatory for Human Rights said Ein Issa and nearby areas fell to IS fighters before noon on July 6.
It comes as Syrian Kurdish fighters captured wide areas in northern Syria from the extremist group, including the strategic town of Tal Abyad, formerly an IS stronghold and a crucial border crossing the IS group used to bring in supplies and foreign fighters and export black-market oil.
Earlier on July 6, the IS group released a video purporting to show the killing of two Syrian men, allegedly for spying on the group.
The video shows two young men in orange jumpsuits, saying they filmed and photographed IS-held areas in Syria and sent footage to a person abroad.
The men are then tied to a tree before being shot in the head at close range by masked gunmen.
