Russia has ordered America to cut the number of diplomatic staff it has in the country and has seized a dacha compound and warehouse used by US officials in retaliation for new sanctions against Moscow.

Embassy staff must leave the country by 1 September, the Foreign Ministry said in a statement, in a move triggered by the US Senate’s near unanimous vote to slap new sanctions on Russia, further hurting its fragile economy.

The move puts Donald Trump in a tough position by forcing him to take a hard line on Moscow or block the legislation and anger his own Republican Party.
