Britain has slapped new sanctions on entities providing military equipment to the Russian military.

The action on Wednesday comes in tandem with Ukrainian President Volodymyr Zelenskyy's visit to Britain the same day.

The sanctions hit seven entities, including a manufacturer of Russian drones and a company that produces parts for helicopters in Russia.

Eight individuals heading firms accused of funding Russian President Vladimir Putin's administration have also been targeted.

The British government says it has sanctioned more than 1,300 individuals and entities since Russia's full-scale invasion of Ukraine began.

Foreign Secretary James Cleverly said, "Russia will have no access to the assets we have frozen until it ends, once and for all, its threats to Ukraine's territorial sovereignty and integrity."
