By making harsh, uncompromising demands in peace talks with Ukraine while continuing to pummel it with waves of missiles and drones, Russian President Vladimir Putin is sending a clear message: He will only accept a settlement on his terms and will keep fighting until they're met.

Moscow’s dual campaign of intensified frontline attacks and bombardment of Ukrainian cities has further reduced the prospects for an end to the fighting.

Russia's defence ministry said on Tuesday that Ukraine, backed by certain European countries, had taken several 'provocative steps' aimed at derailing Moscow-initiated direct peace talks with Kyiv.
