The UK has announced another £1 billion ($1.2 billion) in military aid to Ukraine Wednesday to help it fend off Russia's invasion.

The package will come with air-defence systems and drones.

The UK has allocated £2.3 billion in support of Ukraine since the Russian invasion back in February of this year.

“The package includes sophisticated air-defence systems, uncrewed aerial vehicles, innovative new electronic warfare equipment and thousands of pieces of vital kit for Ukrainian soldiers," said the UK authorities.

British PM Boris Johnson suggested that Vladimir Putin's attacks against Ukraine were "increasingly barbaric" as the Russian leader "fails to make the gains he had anticipated and hoped for and the futility of this war becomes clear to all.”
