MOSCOW -- Russian Foreign Minister Sergei Lavrov said Monday that Kiev launched an overnight drone attack targeting the presidential residence in Russia's northwestern region of Novgorod.

The strike began late Sunday night and continued into the early hours of Monday.

Ukrainian President Volodymyr Zelensky on Monday denied the accusation, calling it "another lie from the Russian Federation".

"They're simply preparing the ground to carry out strikes, probably on the capital and probably on government buildings," Zelensky said.
