The video shows a cache of rockets, mortars, tank shells and other ammunition that terrorists left behind in the cities of Bukamal and Mayadin.
Officials say Israeli-manufactured weapons are among the discovered munitions.
Syrian government forces also found a plant for the production of shells and explosives. A package of documents and barrels of an unspecified liquid that could possibly be used for manufacturing toxic substances was also among the discoveries.
This was not the first time that the Syrian government forces made such discoveries from terrorist hideouts across the country.
In the latest instance last month, Syrian government forces discovered a considerable amount of Israeli-made landmines, toxic materials and munitions left behind by members of Daesh Takfiri terrorist group in the eastern part of Dayr al-Zawr.
