Press TV - Syrian army forces, backed by allied fighters from popular defense groups, have established control over al-Shoula town near the eastern city of Dayr al-Zawr, whose nearly three-year-long�siege, imposed by Daesh Takfiri terrorists, has recently been broken by government forces.

Syria�s official news agency, SANA, citing an unnamed military source, reported that Shoula, which lies some 22 kilometers southwest of Dayr al-Zawr, was fully liberated from the grips of Daesh on Friday after an army operation, supported by the Syrian and Russian air forces, eliminated the last pockets�of terrorists in the town.

It added that the Syrian troops also flushed out terrorists from a number of overlooking hills near�Shoula.

Meanwhile, Syrian government forces, backed by fighter jets, are tightening the noose around Daesh terrorists, who are holed up in Dayr al-Zawr's military airport. Local sources say the troops�are now less than two�kilometers away from the airport and Maqabir district.

The developments came three days after Syrian army units, backed by government and Russian warplanes, managed to reach pro-government forces trapped in the eastern city in a major breakthrough. The move�effectively breached the siege that Daesh militants had laid since January 2015.

Syrian troops and allied volunteer fighters had been advancing for months toward Dayr al-Zawr, the provincial capital city of the oil-rich province of the same name.

Daesh militants overran large parts of Dayr al-Zawr province, including its many oil fields, in mid-2014 as they�seized areas in Syria and neighboring Iraq. By early 2015, the Takfiri terrorists were in control of parts of Dayr al-Zawr city, and besieged the remaining parts of it under government control.

It is estimated that 100,000 people remain in government-held parts of the city. The eastern province served as Daesh's main supply corridor to�Iraq.
