Donald Trump and Vladimir Putin are set to discuss a proposed ceasefire during a crucial phone call - as peace plans in Europe lie in limbo. Kremlin spokesperson Dmitry Peskov today revealed that Russia has sent "additional information" to the US President through special envoy Steve Witkoff - who landed in Moscow on Thursday and met with Putin late in the evening, Peskov said. Once Witkoff has reported to Trump, Russia and the US will discuss potential dates for a phone call between the two leaders, according to Russian state media. "Additional information was provided to the Russian side. Through Witkoff, Putin also passed information and additional signals to Trump," Peskov said. It comes as the US sought Russian agreement on a proposed 30-day ceasefire in Ukraine - accepted by Kyiv during talks in Jeddah on March 11. The agreement saw Washington restart military and intelligence support for Ukraine after stopping it last week. Putin said on Thursday that Russia was prepared to accept the ceasefire but asked that Ukraine paused mobilisation, military training, and foreign aid deliveries as part of the truce. Trump said Putin's remarks "very promising" but that they were "not complete," adding he was open to meeting with the Russian leader. President Volodymyr Zelensky meanwhile called Putin's response "manipulative", suggesting the Russian leader may have been preparing to reject the proposal. "Now we have all heard very predictable, very manipulative words from Putin in response to the idea of silence at the front — he is, in fact, preparing to reject it as of now," Zelensky said in his evening address on March 13. On Thursday, Russia rejected the proposal for a 30-day ceasefire drawn up by the US and Ukraine after a nine-hour meeting in Saudi Arabia on Tuesday. Putin said Ukrainian troops involved in a counter-offensive will have to "surrender or die" before he agrees to a ceasefire. Asked about the ceasefire at a press conference alongside Belarus's president Alexander Lukashenko, Putin thanked Donald Trump for trying to get a deal done - but suggested he would not agree to it in its current form. He said: "We agree with the proposal for a ceasefire to cease hostilities, but we proceed from the fact that this ceasefire should lead to an enduring peace, and should remove the root causes of this crisis." Russia launched a 'full scale invasion' of the country on February 24 2022, sparking an international crisis and threatening to capture Kyiv in the opening days of the war. Ukraine, with strong backing from European allies and the US under Joe Biden, mounted a counter offensive and eventually claimed Russian territory around Kursk.
