ISIS executes 24 after seizing Syrian village

ISIS has executed at least 24 civilians after seizing a village in northern Syria from a US-backed Kurdish-Arab alliance, a monitor said Friday.

The Syrian Observatory for Human Rights said ISIS executed 24 civilians "in the last 24 hours" after taking Buyir from the Syrian Democratic Forces.

The village is located some 10 kilometers northwest of Manbij, a key waypoint between the Turkish border and the ISIS de facto capital of Raqqa city.

ISIS seized control of several villages in the countryside northwest of Manbij since launching a "fierce assault" on Thursday, according to the Observatory, which relies on sources inside Syria for its information.

The SDF, backed by air strikes from a US-led coalition, launched an offensive to retake Manbij from ISIS on May 31.

The alliance managed to enter the town but have since faced fierce opposition from the militants who have fought back with suicide bombers and car bombs.

More than 280,000 have been killed and millions displaced in Syria's five-year conflict.
