Another hostage situation is being reported near Paris.

The scene is unfolding at a post office in Colombes, where AFP reports a gunman is holding two people hostage. It is unknown if the situation is terror-related or if it has any ties to the Charlie Hebdo attack last week.

However, several sources have reported the incident may have to do with a disturbed man complaining about heartbreak.
