| A car bombing in Homs caused widespread damage |
At least 18 people have been killed in a string of explosions in government- and Kurdish-held areas of Syria, state media say.
| The blast caused huge damages in nearby buildings and torched many cars |
Most were killed in the attacks in Tartous, home to the main Russian airbase in Syria.
The city was last hit by bombings in May by so-called Islamic State (IS).
