Retired Gen. Wesley Clark, former NATO supreme allied commander, discusses possible future security guarantees for Ukraine that could help forge a peace agreement.

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.

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.

As Trump pushes for peace, Ukraine accuses Russia of a deadly drone and missile strike, "as if there were no efforts by the world to stop this war."

European NATO leaders must not be naive when discussing a Ukraine peace force but face up to the reality that they would need to deploy tens of thousands of troops to the country for the long term, the head of Germany's soldiers' union said.

President Volodymyr Zelenskyy says a Russian cruise missile hit a U.S. electronics plant in the far west of Ukraine. The strike was part of an overnight barrage of more than 600 drones and missiles.

U.S. and European military planners have begun exploring post-conflict security guarantees for Ukraine, U.S. officials and sources told Reuters on Tuesday, following President Donald Trump's pledge to help protect the country under any deal to end Russia's war.

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.

The gulf between Moscow and Kyiv’s positions remains huge, and that is crashing into the expectations set by the White House.
