Syria's army took control of swathes of the country's north on Saturday, dislodging Kurdish forces from territory over which they held effective autonomy for more than a decade.

The government appeared to be extending its grip on parts of the country under Kurdish control a day after President Ahmed al-Sharaa issued a decree declaring Kurdish a "national language" and granting the minority group official recognition.

The Kurds have said the announcement fell short of their aspirations.
