"Near Dawr az Zawr, six airstrikes struck five ISIL crude oil collection points and an ISIL crude oil pipeline," the release read.
The US Treasury stated earlier that oil sales were among key sources of income for the IS, along with extortion, ransom and external financial supporters.
As part of Operation Inherent Resolve aimed at eliminating the IS, the coalition conducted 14 airstrikes in Syria and six airstrikes in Iraq between 8 a.m. Sunday and 8 a.m. Monday local time (5 a.m. GMT), according to the Central Command's press release.
Last Wednesday, the United States and allies destroyed four oil derricks occupied by the IS terrorist group in Syria.
The US-led coalition has been launching an air campaign against IS, also known as the Islamic State of Iraq and the Levant (ISIL), in Iraq since August and in Syria since September. IS terrorists, known for their brutal tactics, have seized vast areas in both countries and declared an Islamic caliphate in the territories under their control.
