UNITED NATIONS — U.N. Secretary-General Antonio Guterres plans to meet Tuesday with Russian President Vladimir Putin to press for fighting to stop in Ukraine.

The U.N. chief will travel to Moscow for conversations with Putin and Foreign Minister Sergey Lavrov, U.N. spokesperson Eri Kaneko said Friday. She said discussions about a similar visit to Ukraine are under way.

“He wants to discuss with the leadership steps that can be taken right now in order to silence the guns, in order to help the people and in order to allow the people who need to get out” to do so safely, she said.

Guterres asked to meet with both Putin and Ukrainian President Volodymyr Zelenskyy in their respective capitals. Ukraine has welcomed the idea.

Guterres had appealed for a four-day “humanitarian pause” in fighting leading up to Sunday, when Orthodox Christians celebrate Easter.
