Riyadh, October 13 (RHC)-- Saudi Arabia is to increase its supplies of “lethal” weaponry to Takfiri groups operating in Syria, as their reign of terror is diminishing following Russia’s massive anti-terrorist campaign in the war-torn Arab country, a new report says.

Riyadh would dispatch an arsenal of modern, high-powered weaponry, including guided anti-tank weapons, to three foreign-sponsored militant groups of Jaish al-Fatah (the Army of Conquest), the so-called Free Syrian Army (FSA) and the Southern Front, the state-run BBC reported on Thursday, citing an unnamed “well-placed Saudi government official”.

The official further said that Qatar and Turkey had been playing a key role in maintaining the Saudi support for militants fighting against Syrian government forces. He also did not rule out the possibility of supplying surface-to-air missiles to militants.

Russia launched its military operation against terrorists in Syria on September 30 upon a request from the Damascus government, shortly after the upper house of the Russian parliament gave President Vladimir Putin the mandate to use military force in the Arab country.

Since then, Russian air force jet fighters have demolished numerous vehicles, command posts, communication centers, fuel and ammunition depots, plants used for making bombs and improvised explosive devices (IEDs), as well as several training camps, all used by the Daesh Takfiri terrorist group.

For more than four years, Syria has been grappling with a deadly militancy which it blames on some foreign countries, including its northern neighbor, Turkey. Around 250,000 people have lost their lives and millions more have been displaced.
