The UK is sending its first long-range missiles to Ukraine despite a warning from Russian President Vladimir Putin.
He said attacks on Ukraine would increase if Western countries continue supplying Kyiv with long-range weapons.
The UK’s announcement comes the week after the US said it was also supplying a rocket system to Ukraine.
The UK government said the Ukrainian military will be trained in how to use the M270 multiple-launch rocket system launchers in the coming weeks.
Defence Secretary Ben Wallace said the UK was supplying Ukrainian troops with “vital weapons they need to defend their country from unprovoked invasion.
“As Russia’s tactics change, so must our support to Ukraine,” he added.
