An Israeli drone attack targeted and destroyed a weapons depot in the coastal Syrian city of Jableh before daybreak Thursday, the Syrian Observatory for Human Rights reported.

The attack carried out via drones and warplane missiles levelled the depot and caused massive explosions heard from long distances, said the UK-based watchdog group.

It added that the Syrian air defences and Russian forces responded to the attack within 40 to 50 minutes.

The depot is situated near the Hmeimim Air Base, the largest Russian air base in Syria, located in the northwestern province of Latakia.

No immediate reports of casualties have been reported.

While there was no official confirmation, the pro-government Sham FM radio said the sounds heard in the skies over Jableh were the air defences intercepting targets off the coast.

It added that firefighting teams headed to a site in the vicinity of Jableh after columns of fire were seen rising from it, but no information was provided about its nature.

The latest attack follows a series of Israeli airstrikes in Syria this week.

On Wednesday, two Lebanese nationals, including Hassan Jafar Qasir, the son-in-law of late Hezbollah leader Sayyed Hassan Nasrallah, were killed in an Israeli airstrike on a residence in the Mazzeh Western Villas neighbourhood of Damascus.

On Tuesday, an Israeli missile strike hit a site about 500 meters from Wednesday’s target, killing three people, including a journalist, and injuring nine others.

Israel frequently conducted airstrikes in Syria, targeted what it said were positions linked to Iran and Hezbollah.
