Ukrainian Defense Minister Umerov says talks with US officials in Riyadh were successful, and that his country is ready to organize technical discussions on the implementation of a partial truce. The US announced earlier that Russia and Ukraine have agreed to a ceasefire in the Black Sea. Moscow confirmed the agreement, but said it was conditional on sanctions relief, which had not been mentioned in US statements. The agreement also included a 30-day truce against strikes on energy infrastructure.
