A United Nations panel has urged the Security Council to order all countries to seize oil trucks coming in and out of territory controlled by jihadists in Iraq and Syria and to impose a global moratorium on the sale of antiquities from the two countries.

Both oil and antiquities are thought to be vital sources of financing for the groups that call themselves the Islamic State and the Nusra Front.

The recommendations were made by a panel of experts appointed by the United Nations secretary general, Ban Ki-moon, and released late Monday.
