European leaders on Monday, December 15 proposed a European-led "multinational force" with US support to enforce a potential peace deal in Ukraine, as key powers met in Berlin to push forward efforts to end the war.

The force would be part of "robust security guarantees" for Ukraine from the United States and European powers aimed at guaranteeing that Russia would not violate an agreement to end the war, the leaders meeting in Berlin said in a joint statement.

Ukrainian President Volodymyr Zelensky said earlier that talks in the German capital with US President Donald Trump's envoys on ending the war with Russia were "not easy" but brought "real progress" on the question of security guarantees.

Zelensky met for a second day with Trump's special envoy Steve Witkoff and the president's son-in-law Jared Kushner for talks aimed at ending the war that started with Russia's 2022 full-scale invasion, building on a proposal initially put forward by Trump.
