Russia has said its troops are prepared to fire on US positions in Syria if they come under attack by American-backed soldiers 'again'.
The Kremlin accused US forces of 'twice' firing on positions being occupied by the army of Bashar al-Assad, which is fighting alongside Russian special forces to recapture the city of Deir Ezzor from ISIS.
Moscow said the Syrian Democratic Forces, which are being supported by US troops on the ground, opened fire with artillery and mortars, though did not say when.
If this happens again, 'those areas will be immediately suppressed with all military means', Russian commander Major-General Igor Konashenkov said.
Tensions in the region have been rising as the two armies push toward each-other, bringing two world superpowers ever closer to direct conflict.
Both President Trump and President Putin have insisted that their only goal in Syria is to eliminate ISIS, but that has not stopped the pair butting heads.
The most serious incident took place earlier this year when Trump launched 60 cruise missiles at Shayrat Airbase, which is controlled by Assad and had Russian troops stationed there at the time.
The move was retaliation for a gas attack on the town of Khan Sheikhoun which the UN has said was perpetrated by the Assad regime.
Earlier this week the Russian Defence Ministry accused U.S. spies of initiating a jihadi offensive against government-held parts of north-west Syria.
