The UK will supply Ukraine with multiple launch rocket systems that can hit targets at a distance of up to 80 km, Reuters reported.

Defence Secretary Ben Wallace said Britain's support for Ukraine would change as Russia's tactics evolved, explaining the gift of the M270 multiple-launch systems.

"These highly capable multiple-launch rocket systems will enable our Ukrainian friends to better protect themselves against the brutal use of long-range artillery, which (Russian President Vladimir) Putin's forces have used indiscriminately to flatten cities," Wallace said in a statement.

U.S. President Joe Biden said last week that Washington would supply Ukraine with the M142 high-mobility artillery rocket systems, or HIMARS, after he received assurances from Kiev that they would not be used to hit targets in Russian territory.

The U.S. Department of Defense said it would supply Ukraine with four M142 HIMARS systems along with a guided multiple rocket launcher system, which it said had a range of more than 64 kilometers.
