Thousands of soldiers from the Syrian army, Hezbollah and popular forces, backed up by Russian air force, started the final phase of a landmark operation early Tuesday morning and have already come almost half a mile closer to the Kuweires airport Southeast of Aleppo in a region where advance in every inch has taken days.
Kuweires a strategic airbase has been under ISIS siege for two years now.
According to the military source, the pro-government forces are preparing to mop up the rest of Sheikh Ahmad region to prepare for a massive offensive on ISIL positions along the Aleppo-Raqqa Highway.
Some 80 percent of Sheikh Ahmad that is seen as a milestone in the Damascus war on terrorist groups in the Northern province of Aleppo is now under the control of the pro-government forces.
"Commanders of the Syrian Army, popular forces, Hezbollah and Russian Air Force held a meeting in Sheikh Ahmad frontline on Monday to coordinate the last phase of their joint operation for removing the two-year-long ISIL siege on Kuweires airbase, Southeast of Aleppo, according to FNA report."
Last night the pro-government forces were deployed in most parts of Sheikh Ahmad, just 2,600 meters far farm the Southern gates of the strategic Kuweires airbase.
On Sunday, the pro-government forces won a series of tough clashes with militant groups in the Southern part of Sheikh Ahmad and came closer than 3 kilometers to the strategic Kuweires Airbase.
"The joint operations of the Syrian army troops, Hezbollah fighters and NDF that have been underway with the Russian air backup for the last one month have forced the militant groups, specially the ISIL, to withdraw from the Southern parts of Sheikh Ahmad town near the Kuweires airbase."
The sources said that the militant groups have suffered heavy casualties in the latest stage of the pro-government troops' joint operations Saturday night.
The ISIL Takfiri terrorists have besieged the Kuweires airbase for over 2.5 years now, but the base itself is under the Syrian army's control.
Hundreds of Syrian forces are under a tight siege at the airbase as a result of the occupation of vast areas surrounding the airport by the terrorists.
The Syrian army's helicopters supply foodstuff and other needs to the Syrian troops defending the airport.
