The so-called Al-Nusra Front terrorist group, a terrorist movement that in recent months has captured several Lebanese troops in the eastern region of Arsal, threatened on Monday to execute some of the hostages. 

"Wait for surprises regarding the fate of the captured troops," Al-Nusra wrote via Twitter.

Together with its message, the group published photos of some of the troops showing them bound and lying on the ground as five terrorists pointed guns at them.

Al-Nusra, one of several terrorist organizations fighting the Syrian army, captured 17 Lebanese troops.

The so-called 'Islamic State of Iraq and the Levant' (ISIL) terrorist group meanwhile, another armed group that has occupied territories in Iraq, has captured six Lebanese troops.

The two groups captured the soldiers last August following clashes with the Lebanese army in the Lebanese town of Arsal on the Syrian border.

ISIL and Al-Nusra have each executed two of the Lebanese troops that they captured.

On Monday, Lebanese security forces raided a cell in Roumieh Prison in which extremists had been held. Several people from both sides were injured in the ensuing clashes.
