One of the individuals who attacked a church in northern France on Tuesday had prior links to terrorist activities and was briefly held in Geneva after having attempted to travel to Syria.
The Tribune de Genève newspaper reported that the man had previously tried twice without success to travel to Syria, once from Geneva airport. During that attempt, the French citizen was stopped in Turkey on his way and sent back to Geneva. There, he was arrested and spent several days in the Champ-Dollon prison before being extradited to France.
Paris prosecutor François Molins confirmed the report on Tuesday evening.
The Islamic State terror group has claimed responsibility for the latest attack in France.
