Vladimir Putin has said any western troops placed in Ukraine would be “legitimate targets” for Russian strikes, upping the stakes as Kyiv’s allies scramble to come up with a convincing offer of postwar support to Ukraine.

Speaking a day after the French president, Emmanuel Macron, announced still-vague plans for a package of support for Ukraine backed by 26 nations, Putin on Friday said any guarantees that involved boots on the ground would violate Moscow’s longstanding objections to Nato troops in Ukraine.

“Therefore, if some troops appear there, especially now, during military operations, we proceed from the fact that these will be legitimate targets for destruction,” Putin told an economic forum in Vladivostok.
