(MENAFN- Arab News) BEIRUT: Daesh fighters killed at least 37 rival insurgents in an overnight attack in Syria's Aleppo province and 20 fighters remain missing the Syrian Observatory for Human Rights said on Sunday.
Rami Abdulrahman head of the Observatory said that late on Saturday a suicide bomber from the hard-line group blew himself up in a military post held by a group of rival insurgents in the Umm Housh village.
Later Daesh seized full control of Umm Housh which is one of four villages in the northern province of Aleppo that lie along a rebel supply line from Turkey which is a major backer of Syria's opposition.
'Daesh is trying to seize control of these villages from rebels to cut their supply route between Aleppo city and its outskirts and the town of Azaz' a rebel bastion near the border said Observatory head Rami Abdel Rahman.
He said two Daesh suicide bombers one using a suicide belt and one in a bomb-laden car began the assault on the villages on Saturday night.
The ensuing clashes which continued throughout Sunday left at least 37 rebel fighters and 10 Daesh militants dead Abdel Rahman added.
Another twenty rebels were reported missing in action.
Daesh has swept through territory in Iraq and Syria in an effort to build a cross-border 'caliphate' and sees both the regime of Bashar Assad and rival rebel factions as its enemies.
And in recent months the Assad regime has suffered major losses in Syria's north and east as well as near its coastal heartland of Latakia province.
On Sunday a powerful rebel coalition swept through additional villages in the Sahl Al-Ghab plain which borders the provinces of Latakia and Idlib the Observatory said.
The Army of Conquest which includes Al-Qaeda affiliate Al-Nusra Front has edged closer to the regime's regional military headquarters in Jureen.
If the rebels manage to capture Jureen they will be able to advance into the mountains of Latakia and bomb several communities from Assad's Alawite sect.
The Alawite bastion of Latakia city has seen tensions in recent days after a Syrian air force official was killed by Sleiman Assad a cousin of the president.
On Saturday more than 1000 people took to the streets in the city to protest the killing of Col. Hassan Al-Sheikh and to demand the execution of Sleiman Assad.
And on Sunday Syria's official news agency SANA said the death toll from a rebel rocket attacks on the capital Damascus had risen to 11 including three children.
