US expands Russian sanctions and plans to accept 100,000 Ukrainian refugees

• US targets more than half of members of Russia's parliament
• Country to step up assistance for Ukrainians fleeing war

The US has announced new sanctions on more than 400 Russians deemed to be part of the country's elite - including more than half the members of parliament - as part of campaign to increase the price Moscow pays for the invasion of Ukraine, while stepping up assistance to Ukrainians.

The administration also announced it would accept up to 100,000 Ukrainian refugees, almost as many as the current cap for the total number of refugees the US accepts from around the world.
