Video shows the moment a Russian air strike exploded an oil refinery that it claims was controlled by Isis.
The Russian Ministry of Defence released the footage that shows several sections of a large oil refinery burst into flames.
The hit forms part of Russian President Vladimir Putin's decision to intensify air strikes against Isis following reports the Metrojet airliner was brought down by a bomb.
After the recent Paris attacks, French President Francois Hollande and Mr Putin have reportedly agreed to combine their efforts in the region.
Video was also released of Russian air strikes hitting a column of oil tankers in the Syrian desert, which they also claimed belonged to Isis.
Colonel General Andrei Kartapolov announced that "in total 127 sorties were made" against "206 terrorist targets," including the "so-called pipeline on wheels."
