Evacuated Islamic State militants reach extremist stronghold in Syria

These children witnessed torture and beheadings while in Raqqa

Russia's submarines The Veliki Novgorod and The Kolpino have attacked facilities of the Islamic State (outlawed in Russia) with Kalibr cruise missiles from the eastern Mediterranean on Thursday, the Russian Defense Ministry said.

The projectiles destroyed control centers, communication hubs and arms dumps being used by the terrorists, the regime said. The Syrian Government has praised several times the contribution in the fight against terrorism by countries such as Russian Federation and Iran, along with the forces of the Islamic Resistance Movement of Lebanon (Hezbollah). It has repeatedly fired salvoes of such missiles, from both the sea and mainland Russian Federation.

The Syrian Democratic Forces (SDF), a USA -backed alliance of mostly Arab and Kurdish fighters, meanwhile have also launched a separate assault in Deir al-Zor province, which has become Islamic State's last major foothold in Syria.

The convoy was stranded in the desert for about two weeks, even though reports claim that some of the vehicles were able to slip into the militant-held territory.

The Syrian army and Hezbollah, a Shia Lebanese group, had prepared to transport the 17-bus IS convoy containing about 300 fighters and their families to an unspecified area in eastern Syria believed to be near Deir al-Zor.

Syrian government forces recently broke the extremist group's three-year siege on Deir al-Zor as troops advanced on the western side of the city. The U.S. said it did not strike the convoy itself because of the presence of civilians.
