A man with a handgun entered a post office outside of Paris early Friday afternoon, police said.
The incident began around 12:45 p.m. (6:45 a.m. ET).
The gunman might be mentally unstable, according to police in Colombes, a community about 10 kilometers northwest of the French capital. French media reported that he was holding people hostage inside the post office, though authorities didn’t immediately tell CNN one way or another if that’s the case.
Police added that they don’t know yet if the incident is related to terrorism. This is a hot topic in France after last week’s deadly attacks. A Western intelligence source saying there could be as many as 20 terrorist sleeper cells of between 120 and 180 people ready to strike in France, Germany, Belgium and the Netherlands.
