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 improvised explosive devices were thrown at the Russian consulate in the southern French port city of Marseille on Monday, but no one was injured, a police source 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.
