Specialised counterterrorism units have launched coordinated raids across France and arrested at least nine people in connection with the deadly Paris attacks.
Monday's early-morning raids took place in Calais, Toulouse, Paris, Jeumont and Grenoble where police blocked streets and searched houses looking for suspects involved in Friday's attacks, which killed at least 129 people and wounded hundreds more.
Around 200 members of police tactical units surrounded an address in Toulouse according to Al Jazeera correspondent David Chater in Paris, and ammunition and a large amount of cash were also found at one of the locations.
Twenty police vans were used in the raid in Jeumont on the French-Belgian border where a house was searched, added Chater.
Earlier, reports emerged that a fugitive directly involved in the attacks was questioned and let go by police near the Belgian border.
French police had released a photo of Salah Abdeslam, a 26-year-old born in Brussels, who is on the run and too dangerous for anyone outside law enforcement to engage directly.
News of the manhunt came a day after people gathered across France to mark the nation's second day of mourning following the coordinated attacks, apparently carried out by the Islamic State of Iraq and the Levant (ISIL) group.
