The depot, which was found in the town of Aqrab, also contained assault rifles, pistols, Kalashnikov machine guns, mortar shells and sniper rifles, as well as wireless communication devices.
The detection of the depot came as the Syrian Army's engineering units cleared Aqrab of booby traps, ammunition and weapons left by Daesh terrorists before Hama was liberated from the militants.
Last week, SANA reported that Syrian sappers working in the province of Daraa discovered storage facilities with French-made APILAS (Armor-Piercing Infantry Light Arm System) anti-tank systems and US-made TOW anti-tank missiles.
Earlier, Syrian government forces reportedly discovered a huge cache of Western-made arms in Daraa which contained weapons and ammo of various calibers, as well as boxes of supplies delivered to Free Syrian Army (FSA) militants by the United States.
Previously, Abu Shima, head of the information center of the joint operations command of the opposition in the south of Syria, told Sputnik that the leaders of armed groups in Daraa had clinched an agreement with representatives of Russia "on the immediate cessation of hostilities" in the province.
