Abdelhamid
Abaaoud, the alleged mastermind, is said to be the focus of the operation.
The so-called Islamic State
(IS) group has said it carried out the attacks in which 129 people died.
Reports on French TV say two suspects are thought to have
died, including a woman with a suicide belt who has blown herself up. Some
police officers have been wounded in the operation.
The operation began at around 04:30 local time (03:30 GMT).
Deputy Mayor Stephane Peu urged local residents to stay indoors, saying
"it is not a new attack but a police intervention".
Authorities have evacuated about 20 residents from a building
where suspects linked to the Paris attacks are holed up in a standoff with
police.A city official not authorised to be publicly
named told The Associated Press the residents were brought to city hall for
protection. City hall is about 200 m from the apartment building where the
standoff is taking place on rue du Cornillon, in the heart of the historic,
multicultural town just north of Paris. At least seven explosions have been heard at the scene of the
police standoff. Associated Press reporters at the scene could hear what
sounded like grenade blasts from the direction of the standoff in Saint-Denis.
Earlier,
security sources said surveillance video showed a possible ninth assailant
during the attacks. The video reportedly shows a third figure in the car
carrying the group which attacked several bars and restaurants. It is not clear
if this ninth attacker is one of two suspected accomplices detained in Belgium
or is someone still on the run.
