Syrian army launches a massive offensive against Daesh stronghold in southwestern part of Homs province, according to a source.
The terrorists' positions near the city of Palmyra have also been destroyed.
Syria has been mired in civil war since 2011, with government forces loyal to Syrian President Bashar Assad fighting against numerous opposition factions and extremist groups, including Daesh and Nusra Front, outlawed in a number of countries worldwide including Russia.
A US-Russia-brokered ceasefire came into force last Saturday across Syria. It was supported by the Syrian government and dozens of opposition groups on the ground. Daesh and Nusra Front are not part of the deal.
