Political and military leaders in Europe are fleshing out details of a plan for Ukraine once the guns fall silent.

Europeans are split on whether to send troops to Ukraine, with polls showing most citizens in the U.K, Denmark and Germany favor sending in peacekeepers, but elsewhere, the idea of troops getting sucked into the war is very unpopular.

Vladimir Putin claimed to have sent thousands of Russian troops into Ukrainian territory from Kursk, even as the US pushes for peace.

In the shadow of imminent defeat, European powers have unveiled their most audacious military initiative since the end of World War II. As Russia tightens its grip on Ukraine, Britain and France are preparing to cross a line that could potentially reshape the continent's security landscape forever.
