The US has announced new sanctions targeting Russia’s two largest oil companies - Rosneft and Lukoil - in an effort to pressure Moscow to negotiate a peace deal in Ukraine.

“Every time I speak to Vladimir, I have good conversations and then they don’t go anywhere. They just don’t go anywhere,” President Donald Trump said, after a meeting with Nato Secretary-General Mark Rutte to discuss peace negotiations.

He called the sanctions package “tremendous”, and added that he hoped they could be swiftly withdrawn if Russia agrees to stop the war.
