Syria’s army and its allies have encircled Islamic State in the city of al-Mayadin, southeast of Deir al-Zor, in eastern Syria, a Syrian military source said on Sunday, Reuters reported.
Al-Mayadin is one of the last strongholds of Islamic State as it falls back upon the fertile area downstream of Deir al-Zor in the Euphrates valley and launches counter attacks in the central desert region after losing swathes of territory this year.
