Russia has accused the US of allowing Islamic State (IS, ISIS/ISIL) terrorists to move about freely in an area near an American military base in Syria. The Russian Defense Ministry says Moscow wants to know how some 300 Daesh terrorists had passed through the area in pickup trucks.
The ministry adds that the terrorists tried to block the highway between Damascus and Deir Ezzor, which is used to supply Syrian forces.
It also says about 6-hundred terrorists, based in a refugee camp in the US-controlled area had driven en masse to a former customs post on the Syrian-Jordanian border earlier this month.
Russia says the US base and the area around it have become a black hole where terrorists operate unhindered.
The US says the facility is temporarily used to train partner forces to fight against Daesh.
