Biden announces over 500 sanctions on Russia

The United States has announced more than 500 new sanctions against Russia over its invasion of Ukraine and the death of opposition leader Alexei Navalny.

The newly-announced US measures also include nearly 100 firms and individuals which will also face export restrictions.

Others target the state-owned operator of Mir, Russia's main payment system, which has become more prominent since Visa and Mastercard suspended their services there.

US President Joe Biden, who met the critic’s widow and daughter in San Francisco on Thursday, said there can be ‘no doubt’ the Russian president was to blame for his death.

But it is unclear what impact the sanctions will have on Russia's economy.

The EU has also announced new sanctions on access to military technology.
