Original story: An armed man holed up in a post office outside Paris on Friday with two hostages, police told the Agence France-Presse.
"The man equipped with a military weapon took an unconfirmed number of hostages at the post office in the town of Colombes, just outside the capital," Reuters reported.
Law enforcement officials told the AFP that police have cordoned off the area, and helicopters are currently circling overhead.
