Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy each speak by phone with U.S. President Donald Trump on Sunday as Trump marks his 80th birthday. Multiple outlets report the calls happen separately, with both leaders discussing the ongoing war in Ukraine and their views on how a more than four-year conflict could be ended. Russian presidential aide Yuri Ushakov says Putin’s call lasts just under an hour, and that Trump emphasizes the need to end hostilities and expresses readiness to influence European positions. The Hill adds that the calls come while broader U.S. efforts to mediate between Russia and Ukraine are described as stalled. The timing is also linked to developments ahead of this week’s G7 summit, with the Ukraine conflict remaining a central international focus. Other reporting notes separate engagement between Putin, Zelenskyy, and Trump, while the broader backdrop includes ongoing military incidents, including drone strikes reported in Russia and the United Kingdom’s detention of a tanker. Sources present the calls as part of ongoing high-level diplomatic communication rather than announcing a specific new agreement.
