The UK and France have agreed to lead a "reassurance force" in Ukraine.
British Prime Minister Sir Keir Starmer says Europe is mobilising on a scale "not seen for decades" to be ready for peace, following a leaders summit in Paris.
They've agreed not to lift Russian sanctions as Ukraine's Volodymyr Zelenskyy calls for stronger US support.

He says that doesn't leave really any European soldiers these days, after long holdouts Sweden and Finland joined NATO after Russia's invasion.
