Two French scientists admitted to carrying out an attack on the Russian consulate in Marseille using improvised explosive devices, the local newspaper La Provence reported early Wednesday, citing unnamed sources.

Three projectiles were thrown over the perimeter wall of Russia's consulate in the southern French port city of Marseille on Monday, two of which exploded, police said.

French authorities say an incendiary device has exploded outside the Russian Consulate in Marseille on the third anniversary of Russia’s invasion of Ukraine.
