Russian Foreign Minister Sergei Lavrov said on Monday that Ukraine had tried to attack Vladimir Putin’s residence in northern Russia and so Moscow’s negotiating position would be reviewed, but Ukraine said it was a lie.

Russia said Ukraine attacked the presidential residence in the Novgorod region overnight with 91 long-range drones, which were all destroyed by Russian air defences. No one was injured and there was no damage, Lavrov said.

Ukrainian President Volodymyr Zelenskiy said the accusation was a lie, adding that Moscow was preparing the ground to strike government buildings in Kyiv. He said the Russian claim was an attempt to undermine peace talks.
