Russian jets hit Islamic State targets in the Syrian city of Palmyra and the northern province of Aleppo, Syrian television said on Tuesday, quoting a military source.

The strikes destroyed 20 vehicles and three weapons depots in Islamic State-held Palmyra, it said. In Aleppo, they hit the towns of Al-Bab and Deir Hafer, about 20 kilometers east of a military airport currently besieged by Islamic State fighters.

Al-Manar television, run by the Lebanese Hezbollah group which is allied to Syria, said the Russian air force also carried out four raids in the Jabal al-Zawiya area in the northwestern province of Idlib.
