The U.K. has delivered long-range missiles to Ukraine in a move which grants Kyiv the ability to strike targets in Russian-occupied Crimea, writes POLITICO.

Britain’s Defense Secretary Ben Wallace told the House of Commons that the Storm Shadow missiles, promised by Prime Minister Rishi Sunak in February, “are now going into or are in the country itself” and will complement other long-range systems already gifted to the country including HIMARS and Harpoon missiles.

“The donation of these weapons systems gives the Ukrainians the best chance to defend themselves against Russia’s continued brutality, especially the deliberate targeting of Ukrainian civilian infrastructure, which is against international law,” Wallace said.

The Storm Shadow missiles, jointly developed by Britain and France, have arrived in time for Ukraine’s long-anticipated spring counter-offensive against Russian forces. They have a range of about 560 kilometers — the necessary range to strike deep into Russian-occupied territories in Eastern and Southern Ukraine, including Crimea.
