The army men continued cleansing operation in Yalda, Bebeila and Beit Sahm and found a workshop in terrorists’ former positions used for making explosive and poisonous materials.
A large volume of powerful explosives made by a Saudi company was found in the workshop, according to the army officers.
In the meantime, a-kilometer-long network of tunnels was discovered by the army in the region that was used by the terrorists to transfer arms and ammunition to different battlefields.
Also, a large number of landmines, bombs and chemical masks were found in the farms near Yalda, Bebeila and Beit Sahm.
A field commander confirmed in May that the Syrian army’s engineering units found the weapons and ammunition during the clean-up operations in Eastern Qalamoun which recently were evacuated by Jeish al-Islam and al-Nusra.
He added that the Syrian army forces discovered several tanks and a large number of missiles, mortars, anti-tank missiles, different types of ammunition, weapons and bombs which had been hidden by the terrorists in their hideouts.
The sources said that the army units also found a large number of drugs as well as Nitrogen chemicals used by militants to make different types of bombs and mortars that all carried with Turkish and Saudi labels.
The commander said the “footprint of Saudi Arabia and Turkey can readily be traced in all the items found in the region”.
