French police are holding three young Moldovans suspected of being behind graffiti in Paris that show coffins with the slogan "French soldiers in Ukraine," prosecutors said on June 8. "Investigations are continuing. The possibility of foreign interference has not been ruled out at this stage," the Paris Prosecutor's Office told AFP. Eight coffin inscriptions and three others with words written in Cyrillic were discovered on building facades in Paris, said a police source. Three Moldovans were arrested in the same area on the night of June 7-8 "carrying spray paint and stencils that could match," added the same source, who asked not to be named. They are now being questioned in police custody.
