Finance ministers from the 15 nations on the UN Security Council are expected to adopt a resolution aimed at starving the so-called Islamic State of funds.

The draft resolution is based on one that was first passed in 1999 to target the rival jihadist group, al-Qaeda.

It urges countries to “move vigorously and decisively to cut the flow of funds” to IS, such as by preventing its smuggling of oil and antiquities.

The militant group is widely believed to be the world’s wealthiest.

A recent study estimated that it its monthly revenue was $80m (£53m).
