A U.S. air strike has destroyed more than 238 fuel trucks controlled by Islamic State (IS) militants in north-east Syria, the U.S. military has said, according to BBC News.

It is thought the pilots found the trucks parked up together, waiting to be loaded at an oil production point near al-Hasakah and Dayr Az Zawr.

Warning shots were reportedly fired to scare away the civilian drivers, before the destruction of the trucks began.

IS makes large amounts of money from oil it produces from seized facilities.

The U.S. Department of Defense says it will release video of the air raid, which took place over the weekend.

Last week another 116 tankers were destroyed in a previous air strike.

"This was conducted in many ways identical to our last," Pentagon spokesman, Capt Jeff Davis, said on Monday.

"It was proceeded with a leaflet drop to warn drivers out of their trucks as well as a show of force".

Davis said there were no reports of civilian casualties.

The oil lorry strikes are part of Operation Tidal Wave II, a change in tactics on the part of the coalition. Previously, petrol supplies were largely avoided becaU.S.e of the impact on civilian populations.
