What sanctions are there on Russian oil and gas?
The US has announced a complete ban on Russian oil, gas and coal imports, after Ukraine called for sanctions to be expanded.
The UK is to phase out Russian oil by the end of the year, and the EU is reducing its gas imports by two-thirds.
The UK government says this allows enough time for them to find alternative supplies.
Deputy Russian Prime Minister Alexander Novak has said rejecting Russian oil would lead to "catastrophic consequences for the global market".
Oil and gas prices have already risen sharply and could rise yet further if Russia halts exports. But this is not just about fuel, and UK living standards will be hit, with global commodity prices set to soar even higher.
How much oil does Russia export?
Russia is the third biggest producer of oil in the world, behind the US and Saudi Arabia.
Of about five million barrels of crude oil it exports each day, more than half of that goes to Europe.
Russian imports account for 8% of total UK oil demand.
The US is less reliant, with about 3% of its imported oil coming from Russia in 2020.
