UK delivers long-range missiles to Ukraine ahead of counteroffensive.

Britain has supplied Ukraine with Storm Shadow long-range cruise missiles, allowing its forces to hit Russian troops and logistics hubs deep behind the front line. The Kremlin said the reports would require "an adequate response from our military". Britain and other Western countries have scaled up their military aid for Ukraine this year, with Britain saying in January it would send 14 of its main Challenger 2 battle tanks to Ukraine, a pledge that was followed by other nations including the United States and Germany.
