Ukraine has fired US-supplied long-range missiles into Russia for the first time since Joe Biden lifted restrictions on their use – with Moscow warning that it would respond “accordingly” on a day where Vladimir Putin lowered the bar for the Kremlin to launch an attack using nuclear weapons.
Ukraine used the Army Tactical Missile System (ATACMS) in a strike on Russia’s Bryansk region, about 80 miles (130 kilometres) from the border.
