"Russia resorts ... to lies and manipulation of our public opinions, in particular by financing interference, promoting false media, and accusing Ukraine," Sejourne said at a press conference in Paris with U.S. Secretary of State Antony Blinken.

Labelling as "crude" Russia's efforts to blame Ukraine for an attack in Moscow that was claimed by a branch of Islamic State, he said Europe was determined to stop Russian efforts to destabilise the bloc.

"I will propose a sanctions regime against those who support disinformation and destabilisation in or country and Europe as a whole," Sejourne said.
