Takfiri groups have stepped up their terror campaign against Syrians in several cities and towns as the country prepares for the presidential election on June 3.
Meanwhile, Syrian forces have regained full control over Height 724 north of Kasab village near the port city of Lattakia.
Government troops have killed 40 armed men and injured 70 more in Kasab.

Syria has been gripped by deadly violence since March 2011. According to some reports, over 150,000 people have been killed and millions displaced due to the violence fueled by the foreign-backed insurgents.
