Police: Armed man surrenders after Paris standoff

Updated at 7:25 a.m. ET: PARIS - An armed man briefly took an adult hostage at a nursery school south of Paris on Tuesday. 

The intruder, who entered the school in Vitry-sur-Seine on the southern edge of the capital shortly before opening time, freed the hostage after a few hours and later surrendered to police, said Ludovic Monier, a policeman at the scene.

"At 12.10 (6:10 a.m. ET) the hostage-taker was taken out (of the building) calmly ... without any shots fired," Monier told reporters. 

Some children were initially also taken hostage but were released unharmed.
