The town of Abu Kemal in the Deir ez-Zor province has been considered the last ISIS terrorist group's stronghold after the liberation of al-Mayadin by the Syrian government forces.

The Syrian army command confirmed Thursday that it fully regained control over the city of Abu Kemal, destroying the last ISIS stronghold.

"The Syrian army and allied forces liberated the city of Abu Kemal in Deir ez-Zor province, the last stronghold of the IS [ISIS] terrorist group in the east," the statement read.

The forces are patrolling the town to clear it of mines and explosive devices.

"Abu Kemal is the last ISIS stronghold, but we should understand that terrorists are changing their tactics and can follow a guerilla strategy," military analyst Andrei Koshkin said.
