European leaders propose a 40-km buffer zone between Ukraine and Russia, with mixed reactions.

European leaders are considering a 40-kilometer buffer zone between Ukrainian and Russian forces as part of a potential peace agreement. Moscow supports the idea, but Kyiv's acceptance is uncertain due to concerns over territorial concessions. The proposal faces criticism for potentially prolonging the conflict and undermining Ukraine's sovereignty. The number of troops needed to secure the zone is also undetermined, ranging from 4,000 to 60,000. The U.S. is not involved in these discussions.
