US-led airstrikes on Friday destroyed four tanks of the Islamic State in Syria (ISIS) terrorist group at Deir el-Zour, eastern section of Syria.

During its second day of attack, the American-led coalition targeted ISIS-controlled oil depots which are reportedly providing the terrorist group millions of dollars daily. Previous air strikes Wednesday also destroyed  ISIS-controlled oil producing facilities.

The ISIS is able to sell an average of US$2 million per day in the oil black market. The revenue is being used to recruit and train young fighters from different parts of the world.

The group uses online social media networks such as Facebook, YouTube and Twitter to entice young men to join ISIS.

The airstrikes have also destroyed ISIS oil fields and mobile facilties in Tanak and in Qouriyeh, Deir el-Zhour on Friday.

Aside from oil depots, airstrikes also targeted ISIS training fields, checkpoints, vehicles, and its headquarters and offices, such as those in Mayadeen district southeast of Deir el-Zour.

"People living around the ISIS buildings are vacating the place and are moving towards villages where there are no strong presence of ISIS," said by Syrian Human Rights Observatory Director Rami Abdurrahman.

Abdurrahman added that airstrikes outside the Hassakeh City north eastern Syria are likely to happen in the days to come.
