U.S. special envoy Steve Witkoff met with Russian President Vladimir Putin in Moscow on Tuesday, taking a draft peace plan that Washington hopes can bring about an end to the nearly four-year war in Ukraine.

Putin, however, ahead of the talks accused Ukraine’s European allies of sabotaging U.S.-led efforts to end the war, calling their demands “absolutely unacceptable.”

U.S. President Donald Trump's son-in-law Jared Kushner would join the meeting, Kremlin spokesman Dmitry Peskov told reporters. He said the talks would take “as long as needed” and involve only Witkoff, Kushner and an interpreter from the U.S. side.

Meanwhile, Ukrainian President Volodymyr Zelenskyy was in Ireland during his European tour to sustain support against Russia’s invasion.

According to a draft of Trump's plan obtained last month by The Associated Press, it would cede land to Russia and limit the size of Kyiv’s military. Ukraine and European allies have been working with U.S. officials to amend the plan.
