"The Syrian army exploded one of the major military sites of Liwa Fajr al-Ummah, affiliated to Ajnad al-Sham, in Harasta,” the sources said.
"Several explosions occurred as a result of the army attack, which left many terrorists dead or wounded,” the army added.
"The terrorist groups had stored a large volume of ammunition inside the site, and the first explosion caused the other explosions in the depot,” the army went on to say.
Militant groups’ positions in different parts of Damascus province have been under the massive attacks of the Syrian army, air force, and artillery units in the recent weeks.
Sources said earlier today that two main districts in the Eastern and Northeastern outskirts of the Capital were the scenes of the Syrian government forces’ heavy attacks on the militant groups’ strongholds, adding the militants left behind many dead members and fled the battlefronts.
"The militant groups’ fortified positions in Zamalka in the Northeastern outskirt of Damascus came under massive offensive of the Syrian army and its allies,” the sources said.
"The pro-government forces killed or wounded many terrorists and destroyed their military hardware,” the army added.
"The Syrian forces’ attack on al-Nusra Front’s gatherings in Ein Tarma in the Eastern side of Damascus killed dozens of the terrorists, including a Yemeni and two field commanders on the group,” the army went on to say.
