Russian President Vladimir Putin has announced that 755 staff must leave US diplomatic missions, in retaliation for new US sanctions against Moscow.
The decision to expel staff was made on Saturday but Putin has now confirmed the number that must go by 1st September.
It brings staff levels to 455, the same as Russia's complement in Washington.
This is thought to be the largest expulsion of diplomats from any country in modern history.
Russia has also said it is seizing holiday properties and a warehouse used by US diplomats.
