Russia has vowed an "appropriate" response if Ukraine uses US long-range missiles to strike its territory

The Kremlin warns Kyiv's use of such missiles would mark an escalation in the conflict, hours after US officials say Joe Biden has given the green light

Biden tells leaders at the G20 summit in Brazil the US strongly supports Ukraine’s sovereignty and territorial integrity. Ukrainian President Volodymyr Zelensky has said "the missiles will speak for themselves"

The US will reportedly allow Ukraine to use the missiles to hold onto the small chunk of Russian territory it occupies in Kursk, reportingly making the decision after the Kremlin allowed North Korean troops to fight there

Meanwhile at least 10 people have been killed after a missile was shot down and fell on residential buildings in Odesa, following a weekend of widespread Russian attacks
