One person was killed in a Ukrainian attack on Russian-occupied Crimea, established officials in Moscow said in the early hours of Sunday, as the Russian and Ukrainian presidents held separate talks with US President Donald Trump to end the war, now in its fifth year.Two others were injured in the attack in northern Crimea, one of them in serious condition, Russia-installed regional governor Sergei Aksyonov wrote on Telegram. He did not give details of the attack. Ukraine has stepped up its attacks on key infrastructure targets in Crimea in recent weeks as Kiev’s forces seek to isolate the vital Russian-held peninsula in the latest phase of the war.The latest attacks came after Ukrainian President Volodymyr Zelensky and Russian President Vladimir Putin spoke to Trump about ending the war. Writing on X, Zelensky said he had called Trump to congratulate him on the 250th anniversary of US independence and the two leaders discussed the situation on the front line. “There is a real possibility of this war ending and America’s determination will be critical. “We agreed to continue the talks in person during the NATO summit in Ankara.”The Kremlin said Putin and Trump discussed the conflict in Ukraine in a “constructive” phone call on Saturday. Kremlin foreign affairs adviser Yuri Ushakov said Putin congratulated Trump and the American people on the 250th anniversary of America’s independence during the call that lasted about an hour and a half, their fourth conversation so far this year.Ushakov said Trump reaffirmed his readiness to help Ukraine quickly end hostilities and find a peaceful solution to the crisis, while Trump’s envoys Steve Witkoff and Jared Kushner will continue mediation efforts. The Kremlin adviser said Putin once again stressed Russia’s “priority for a diplomatic resolution of the conflict, provided that Russia’s fundamental position is taken into account.”“Putin charged that Kiev and European allies are “betting on prolonging the conflict and even escalating it,” arguing that “the European ‘party of war’ proceeds from a flawed perception of the overall situation,” Ushakov said.
