Russian jet fighters continue its anti-terror mission in Syria by targeting oil tankers owned by the Islamic State of Iraq and Syria (ISIS), thus undermining the group’s financial resources.

A new footage filmed by ISIS jihadists shows a number of charred oil tankers after being hit by Russian airstrikes in al-Mansurah town located nearly 20 km to the southwest of the group’s de facto capital of al-Raqqa.

ISIS, a notorious death cult known for its barbaric executions, is illegally trading with stolen Syrian and Iraqi oil to finance its bloodthirsty jihadists and purchase weapons.

The destination of the destroyed tankers is still unknown.

ISIS has been financially crippled as Russian and U.S. airstrikes have been frequently targeting the group’s banks, oil refineries and tankers.
