Russia’s foreign minister has cast fresh doubt on peace talks, questioning “the legitimacy” of Ukrainian president Volodymyr Zelensky to sign any future agreements after targetting a US factory in a large bombardment on Ukraine.

Russia struck an American business with cruise missiles overnight in one of the largest aerial attacks of the war so far, Ukraine has said.

Nearly a week after President Trump’s Alaska summit, his suggestions of imminent breakthroughs have not come to pass.

NATO defense chiefs are holding a virtual meeting to discuss security guarantees for Ukraine as part of efforts to end Russia's war on its neighbor.

The fast-moving developments in Trump's near-back-to-back summits with the heads of Russia, Ukraine and European powers have highlighted a pair of repeated sticking points.

European leaders are discussing a security guarantee for Ukraine that would commit Kyiv’s allies to decide within 24 hours whether to provide military support to the country if it’s again attacked by Russia.

NATO's top military officials emerged from talks without a concrete plan to guarantee Ukraine's security – at least not one they were willing to discuss publicly.

Russia has yet again ignored Donald Trump’s bid to hold a summit between Vladimir Putin and Volodymyr Zelensky and said attempts to resolve security issues for Kyiv without Moscow’s participation was a “road to nowhere”.
