Moscow threw Donald Trump’s Ukraine peace initiative into disarray on Thursday, insisting it must have a veto over any postwar support for the country as its forces carried out a large-scale overnight missile barrage.

In a series of hardline remarks, Russia’s foreign minister, Sergei Lavrov, said European proposals to deploy troops in Ukraine after a settlement would amount to “foreign intervention”, which he called absolutely unacceptable for Russia.

Lavrov said Russia wanted to return to discussing a framework first proposed during the initial peace talks held in Istanbul in 2022, under which Moscow and Beijing would help guarantee Ukraine’s security alongside European allies – terms Kyiv considers unacceptable.
