(FNA) -- Mohanad al-Talla'a, the commander of FSA-affiliated Jeish al-Maqawir, said that the new base is set up in al-Zakaf region 60km Northeast of al-Tanf base and with 130km distance to the town of Albu Kamal (Abu Kamal) in Eastern Deir Ezzur.
He claimed that the new base has been established to train fighters round the clock to fight ISIL.
Al-Talla'a added that the base which has been established with the back up of the US-led coalition will be used for the launch of small and mid-size operations in Syria's Badiyeh (desert).
Another source in Jeish al-Maqawir reported that a large volume of arms and ammunition and a large number of militants affiliated to terrorist groups and the coalition have been deployed at the base.
Intelligent agents reported early in May that the US, British and Jordanian forces were preparing for a possible invasion of Syria under the pretext of war on ISIL terrorists.
According to reports, Damascus went on the alert after intelligence reports gathered from surveillance drones suggested that the US, Britain and Jordanian militaries might be prepping a massive invasion of Syria.
Nearly 400 American and Jordanian military vehicles were located at a Jordanian military base near the Syrian desert border, the reports said, adding there was no ISIL terrorists in the region in which the US, British and Jordanian forces were operating.
The reports further added that activities of these three countries at border were aimed at gathering Arab and Western forces in al-Zarqa camp in which there were almost 4,500 gunmen.
The report went on to say that the gunmen in al-Zarqa camp went under training to battle the Syrian army to stretch a belt around Syria, a plan that was nothing more than an occupation.
The intelligence reports also said that the military convoys of the US, Jordan and Britain might launch an assault to help the West-backed FSA around the al-Tanf border crossing.
Reports also said that the Syrian Army troops, in response to the possible attacks by the US, British and Jordanian forces on their soil, launched a large-scale operation along the Damascus-Baghdad highway to drive FSA out of the border crossing of al-Tanf.
