Paris, Jan 9 (IANS) French police Friday surrounded a building in a town northeast of Paris where two men who killed 12 people at the office of French satirical magazine Charlie Hebdo, are said to be holding a hostage, BBC reported.

Shots were fired and several people are said to have been wounded as the gunmen hijacked a car.

French Interior Minister Bernard Cazeneuve confirmed the operation in Dammartin-en-Goele, 35 km from Paris.

The development comes nearly 48 hours since the attack on the magazine’s office, when 12 people were shot dead.

The heavily armed gunmen fled Paris by car after the attack.

The attackers, who shouted Islamist slogans, are believed to have been angered by the satirical magazine’s irreverent depictions of the Prophet Muhammad.
