An armed man has taken†an unspecified number of people†hostage at a post office in Colombes, northwest of Paris. It could not be ascertained at press time if the hostage-taking was another terrorist act. While that could not be established, a source affirmed to Reuters it was not related to last week twin attacks in the city. Related, French police arrested 12 people on Friday, who are suspected of helping militant Islamist gunmen in last week’s killings. The police is also being careful, as there have been numerous false alerts across the city since the attacks.
