Security forces cordoned off the area, and several police officers stood with their weapons drawn at the building, according to a witness. He spoke on condition of anonymity for his security.
Paris police spokeswoman Johana Primevert says officers deployed today after shots rang out and the gunman later surrendered to police.
The building is at the junction of the Rue de Bichat and Rue du Faubourg du Temple in eastern Paris, near two cafes targeted in the November 13 Islamic State attacks that left 130 people dead and wounded hundreds.
