The People’s Protection Units (YPG) on Monday wrestled the Serin town in northern Syria from ISIS, after a month of fierce offensive, the Syrian Observatory for Human Rights (SOHR) said.
Serin, a town near the Euphrates River, was a launchpad for ISIS to wage raids on YPG-held Turkish-Syrian-border city of Kobani.
Kobani was captured by the YPG - backed by the US-led coalition air strikes - on January after a siege that lasted for four months against ISIS.
ISIS loss of Kobani, also known as Ayn al Arab, was seen as a significant defeat regarding the amount of extensive military resources they invested in to capture the isolated town on the border with Turkey.
On June 21, the YPG captured another border town,Tal Abyad, from ISIS.
The capture of Tal Abyad means that YPG effectively controls some 400 km of the Syrian-Turkish border.
The YPG now controls the border from Syria’s northeastern corner to the town of Jarabulus, held by ISIS, the last remaining border crossing with Turkey.
Tal Abyad is an oil-rich city located 65 kilometres east of Kobani and a key city between Turkey and the northern Syrian province of Raqqa, ISIS’ main stronghold and capital of the claimed “caliphate” State.
In an interview with Salih Muslim, the co-chairman of PYD, Kurdish Democratic Union Party, posted by London-based Al Hayat newspaper, he said YPG fighters - including Kurds, Arabs Turkmen and Syriacs - had broken ISIS.
Muslim claimed that ISIS had used chemical weapons in its attacks on YPG positions, in particular in the province of Hasakah.
”A statement was issued [by PYD] calling the International organizations to make investigations about this,” he said.
ISIS currently holds control over large swaths of territory, stretching eastward from the outskirts of Aleppo, Syria’s largest city, to western Iraq.
