Secretary of State Marco Rubio told European counterparts Thursday the US will participate in post-war security guarantees for Ukraine but that the Trump administration believes Europe should take the lead,

Russian Foreign Minister Sergei Lavrov said Wednesday that talks about a security guarantee for Ukraine – against Russia – must involve Moscow itself. "Moscow won't agree with collective security guarantees negotiated without Russia," he said, implying a Russian veto over defenses for Ukraine.

The Kremlin’s goal is to destabilize Europe, and attacks on infrastructure are a preferred weapon, a new report said.

Russia attacked a civilian factory in western Ukraine owned by US company Flex Ltd, causing a massive fire and wounding at least 19 people.
