Mohammed Nassour told us on Sunday that the Syrian army and Hezbollah fighters also dealt heavy blows to other insurgent groups in Qusayr clashes.

Latest reports indicate that the Syrian army has also pushed foreign - backed militants out of the central villages of Salhiyeh and Masoudiyeh, just north of Qusayr. It is now in control of several villages near Qusayr in Homs province.

The al - Nusra Front has been behind many of the deadly bombings targeting both civilians and government institutions across Syria since the outbreak of violence in March 2011.

On May 10, Syria’s Ambassador to the UN Bashar al - Ja’afari said the al - Nusra Front has claimed responsibility for carrying out at least 600 acts of terror in the past year. Ja’afari also slammed the group for attacking hospitals and schools, desecrating holy places, assassinating religious figures, and abducting UN personnel in Syria.

The West has been widely criticized for its double standard when it comes to dealing with terrorist groups.

Over two years of foreign - sponsored militancy in Syria has taken its toll on the lives of many people, including large numbers of Syrian soldiers and security personnel.
