French police arrested three people on Tuesday in connection with the deadly Paris attacks of last month and Charlie Hebdo attacks in January.
Seperately, a French teacher who invented a DAESH attack story was hospitalised to undergo psychiatric tests.
A 29-year-old man was arrested in affiliation with November 13 attacks which were carried out by DAESH terrorists, killing 130 civilians and injuring more than 300 others in Paris.
There have been 2,700 police raids in France since the attacks.
Interior Minister Bernard Cazeneuve said a total of 334 people had been arrested since the attacks, of whom 287 were held for questioning, and that over 400 weapons had been seized.
Three of the nine attackers have yet to be identified, including two of the three suicide bombers, who appear to have used fake passports to pose as refugees.
Salah Abdeslam, a French citizen who is thought to have played a key logistical role in the attacks, is still on the run and subject to an international arrest warrant.
Two people were also questioned in relation to the January attacks on suspicion of supplying weapons to one of the gunmen, Amedy Coulibaly, who attacked a Jewish supermarket .
He had killed four people in the supermarket and a policewoman, before being shot by the police.
One of those arrested, Claude Hermant, was said by prosecutors to have links to far-right groups.
He was also charged with arms trafficking earlier this year.
