Ukraine-Russia border ‘demilitarised zone’ floated for peace deal covering the Russian regions of Belgorod, Bryansk, Kursk and Rostov

A demilitarised zone between 100 and 120 kilometres wide (62 to 75 miles) should be established in Russian border territory with Ukraine as part of any post-war settlement, an adviser to Ukraine’s presidential office has said.

Mykhailo Podolyak, the adviser to the head of the Office of the President of Ukraine, said the demilitarised zone should cover the Russian regions of Belgorod, Bryansk, Kursk and Rostov in order to protect adjacent territories in Ukraine.
