Strikes by the US-led air coalition fighting the Islamic State group destroyed 116 fuel trucks used by the jihadist organisation in eastern Syria, the Pentagon said on Monday.
In a statement, the Pentagon said the trucks were destroyed in a single strike on Sunday near Albu Kamal, an IS-held town in Deir Ezzor province along Syria's border with Iraq.
IS controls most of the oil-rich Deir Ezzor province and part of the city, but has tried for months to seize all of the provincial capital.
Coalition forces conducted 10 strikes in northern, central, and eastern Syria on Sunday, in one of the highest number of raids for the campaign in weeks.
The statement said 13 strikes were carried out in various parts of Iraq on Sunday as well.
IS has declared a self-styled caliphate in swathes of territory it seized in Iraq and Syria but has faced recent setbacks from Kurdish and Arab forces in Iraq's Sinjar and parts of northeastern Syria.
