The Kremlin denied on Tuesday that it was behind media and internet attacks on the campaign of French presidential front-runner Emmanuel Macron though his camp renewed the charges against Russian media and a hackers' group operating in Ukraine.

Kremlin spokesman Dmitry Peskov, replying to a question on a daily conference call, said charges made by Macron's party chief, Richard Ferrand, were absurd.

"We didn't have, and do not have, any intention of interfering in the internal affairs of other countries, or in their electoral processes in particular," Peskov told reporters.
