Russian leader Vladimir Putin told US President Donald Trump by telephone on Thursday that Moscow will not "give up" on its aims in Ukraine, the Kremlin said. The pair spoke as US-led peace talks on ending the more than three-year-old conflict in Ukraine have stalled and after Washington paused some weapons shipments to Kyiv.
