PARIS, Jan. 9 -- The Office of Paris Prosecutor of the Republic confirms that there was no victim in Friday morning's shooting.

Local RTL radio reported earlier that one person was killed and several others were injured before a hostage-taking in Dammartin-en-Goele, northeast Paris.

"An operation is underway which is set to neutralize the perpetrators of the cowardly attack carried out two days ago," French Interior Minister Bernard Cazeneuve said in a televised statement.

Gunshots were heard Friday morning during a car chase north-east of Paris with two suspects who thought to be the brothers carrying out the armed attack at the headquarters of the Paris-based Charlie Hebdo satirical weekly.

A woman alerted the police this morning, saying her grey Peugeot 206 was stolen by the Kouachi brothers that she "surely recognized."

Suspects have taken hostages in a company in Damartin-en-Goele, but the number is still unknown.

Another witness working next to the company said she heard four gunshots this morning.

Manhunt for two fugitives, widened with heavily-armed anti-terrorism units, started Thursday, after a witness of a gas station told the police that he "surely recognized the two men."
