600 members of the ISIS terrorist group were killed and many more were wounded in the Syrian government forces' operations across the country in the recent three weeks.
The majority of the death toll seems to have been inflicted by the Syrian army and Russian Airforce in Eastern Aleppo (Kuweires Airbase), Southern Aleppo (Khanasser), Eastern Homs (Palmyra and Quaryatayn) and Deir Ezzur city.
The ISIS also has lost 3,000 square kilometers (1,160 square miles) in the last three weeks.
A reports by opposition groups said on Tuesday that 44,992 terrorists were killed in clashes with the Syrian Army and its allies during nearly five years of bloody crisis in the country.
"Nearly 45,000 members of the ISIS, al-Nusra Front, Ajnad al-Sham, Jund al-Aqsa, al-Hizb al-Turkistani, Janoud al-Sham al-Shishan and Kata'ebat al-Khadhra have thus far been killed in battles with the Syrian government forces across Syria," the sources said.
