Syrian troops fighting Kurdish forces in north-eastern Syria have seized the country's largest oilfield.

The Omar facility and nearby gas fields are under army control after the Kurdish-led Syrian Democratic Forces (SDF) pulled back, officials and monitors say. Earlier the army captured the strategic Tabqa dam on the Euphrates river.

The push came after the SDF announced it would redeploy east of the Euphrates, following deadly clashes last week. That withdrawal followed talks with US officials.

Ongoing fighting in the area stems from the breakdown of an agreement between SDF and the government of President Ahmed al-Sharaa, who is seeking to integrate Kurdish bodies into Syrian institutions.

On Friday, in an apparent good-will gesture, al-Sharaa said he would make Kurdish a national language and make the Kurdish new year an official holiday. The decree is the first formal recognition of Kurdish national rights since Syria's independence in 1946.
