A US official confirms that the joint US-led airstrikes are now targeting oil installations.
Islamic State is estimated to be making between $1 and $3m per day from oil sales, thanks to oil produced at fields in Raqqa and Deir Ezzor.
CNN reports that US and Emirati planes are now launching airstrikes against fields in remote areas of northern Syria.
Officials told the channel to "expect oil fires" as the allies launch a systematic campaign against IS-run installations.
