Ukraine’s allies made promises of air defence munitions in the wake of a deadly wave of long-range bombardments against civilian and military targets by Moscow.

More than 50 people were killed in an attack on a military academy in the central city of Poltava, while a day later a missile barrage on western Lviv wiped out an entire family apart from the father.

John Healey, the Defence Secretary, promised to send 650 air-defence missiles to Ukraine, in a support package worth £162 million.

“These new UK-made missiles will support Ukraine to defend its people, infrastructure and territory from Putin’s brutal attacks,” he said.

Lloyd Austin, the US defence secretary, announced a $250m (£191m) package, expected to include air defence.

“We hear your urgency and we share it,” Mr Austin said.

Germany said it would deliver four Iris-T air-defence batteries and 10 Gepard anti-aircraft tanks.

Standing next to Mr Zelensky, Mr Healey pledged to extend the UK’s Operation Interflex training programme for Ukrainian recruits through next year.

“As I told our allies and partners today in Germany, the UK will continue to step up our support. We will stand with Ukraine for as long as it takes,” the Defence Secretary said.

The scheme has trained more than 45,000 Ukrainian troops since the beginning of Putin’s invasion in February 2022.

The US package also includes Bradley infantry fighting vehicles, ammunition for Himars rocket launchers and patrol boats.
