The anti-Isis coalition has released footage of air strikes that exploded 283 oil trucks belonging to the militant group.
The air strikes were conducted over the weekend in eastern Syria by the Combined Joint Task Force (CJTF).
One of the coalition's aims is to reduce Isis's production of oil, which the CJTF report generates 2/3 of the group's revenue from black market trading.
The New York Times has estimated that Isis can earn $40 million a month through selling oil on the black market.
The air strikes were conducted near al-Hasakah and Deir ez-Zor in eastern Syria, using A-10 Warthogs and AC-130 Specter Gunships.
The targets were destroyed using a combination of precision-guided bomba and low-flying aircraft cannon fire.
The Russian Ministry of Defence recently reported similar success in targeting Isis's oil production, hitting an oil refinery and several trucks.
The CJTF was set up by US Central Command, with the support of over 30 countries including the UK. Current operations targeting Isis's illegal oil revenue are named Operation Tidal Wave II.
