Russia has warned that trying to resolve Ukraine’s security issues without its involvement is a “road to nowhere,” Russian Foreign Minister Sergey Lavrov said Wednesday. He stressed that any summit between Putin and Zelenskiy must be carefully prepared to avoid worsening the conflict, Al Jazeera reported.

Ukraine, meanwhile, is coordinating with European and NATO advisers on military security guarantees. Zelenskiy’s chief of staff, Andriy Yermak, said Moscow must act promptly or face stronger international pressure, adding that Ukraine is ready for talks on a fair end to the war.
