Britain on Friday announced a “surge” of military support to Ukraine, as the war-ravaged country’s Western backers gathered to drum up more weapons and ammunition to fight off Russia’s invasion and a US envoy flew to Moscow amid ongoing ceasefire efforts.

Britain said that in a joint effort with Norway just over $580 million would be spent to provide hundreds of thousands of military drones, radar systems and anti-tank mines, as well as repair and maintenance contracts to keep Ukrainian armoured vehicles on the battlefield.
