U.S. President Donald Trumpis expected to speak with his Russian counterpart Vladimir Putinthis week on ways to end the three-year war in Ukraine, U.S. envoy Steve Witkoff told CNN on Sunday after returning from what he described as a "positive" meeting with Putin in Moscow.

The Kremlin is pressing an offensive to take back its land in the Kursk region, while prolonging negotiations over a proposal by Washington and Kyiv.

The stationing of peacekeeping troops in Ukraine, as proposed by Britain and France as part of a ceasefire agreement with Russia, is a question for Kyiv to decide and not Moscow, French President Emmanuel Macron said in an interview.

Russia is seeking an "ironclad" guarantee that Ukraine is barred from NATO and foreign troops stay out, a deputy foreign minister for the Kremlin said.
