(BBC News) The United States Agency for International Development (USAID) has announced it will close its offices in Russia following an order from the authorities there to cease operations.

The Russian government gave the US until 1 October to close the mission, accusing it of meddling in politics.

USAID has worked in Russia for two decades, spending nearly $3bn (£1.8bn) on aid and democratic programmes.

The expulsion follows a government crackdown on pro-democracy groups.
