The president says he wants Opec and Saudi Arabia to bring down the price of oil which he says is fuelling the Russia-Ukraine war.

President Donald Trump called on the Organization of the Petroleum Exporting Countries to lower oil prices during the World Economic Forum on Thursday, saying it would immediately end the war in Ukraine.

"You've got to bring down the oil price, you've got to end that war. They should have done it long ago," President Donald Trump said.
