German Chancellor Friedrich Merz has pledged to help Ukraine develop its own long-range missile systems that would be free of any Western-imposed limitations on their range and targets.

Germany and Ukraine strike a deal to jointly develop weapons with "no range restrictions," as the Kremlin says Trump's jabs at Putin are due to him "not being informed."

Germany has given Ukraine the green light to strike targets inside Russia using long-range weapons supplied by Berlin, in a decision that signals a notable hardening of Western resolve as the war grinds on.
