ANKARA (Reuters) - Turkey is ready to host negotiations for a ceasefire and permanent peace between Russia and Ukraine, President Tayyip Erdogan told his French counterpart Emmanuel Macron in a phone call on Sunday, Erdogan's office said.

U.S. President Donald Trump's senior envoys Steve Witkoff and Keith Kellogg will travel to Istanbul for potential talks on Thursday on how to end the war in Ukraine, three sources familiar with the plans said on Tuesday.

Both Moscow and Kyiv each accused the other of violating a truce Ukraine had never agreed to — even as it prompted Ukraine, with backing from European leaders (France, Germany, the United Kingdom and Poland) and the United States (it seems), to demand an extended 30-day ceasefire from the Kremlin.

Ukrainian President Volodymyr Zelensky says he will be present in Turkey for direct negotiations with Russian President Vladimir Putin, telling CNN’s Nick Paton Walsh he expects new sanctions to be imposed on Russia if a 30-day unconditional ceasefire isn’t agreed upon.
