US-led coalition warplanes have struck an oil refinery controlled by the Islamic State group inside Syria, residents of a Turkish border town said.
They claimed the air strikes hit the Tel Abyad refinery in the early hours of Sunday, a few hundred yards from the Turkish town of Akcakale.
The US-led coalition has been targeting oil installations controlled by the militants, aiming to cripple the Islamic State group’s revenue sources, estimated at some $3m a day.
The United States and five Arab allies launched an aerial campaign against Islamic State fighters on Tuesday, with the aim of rolling back and ultimately crushing the extremist group, which has created a proto-state spanning the Syria-Iraq border.
