AKIPRESS.COM - Twelve suspects are being held by police in the Paris region over last week's attacks in the French capital that killed 17, reports say.

They are being questioned about "possible logistical support", such as weapons or vehicles, that they could have given the gunmen, a judicial source told AFP.

Police conducted raids in five towns in the Paris region, iTele reported.

Last week's violence began with an attack on the Charlie Hebdo magazine.

Twelve people were killed at the Charlie Hebdo offices by two gunmen, and four by another gunman at a kosher supermarket. The following day a policewoman was shot dead while responding to a traffic accident.

All three gunmen were later shot dead by police.

In the latest development, police carried out raids in the towns of Montrouge, Grigny, Chatenay-Malabry, Epinay-sur-Seine and Fleury-Merogis overnight, iTele reported.

Also on Friday, the Gare de l'Est train station in Paris was evacuated for an hour over a bomb threat, train operator SNCF told the BBC. Services resumed at 09:00 local time (08:00 GMT), SNCF said, without giving further details.

Spain has also launched an inquiry after it was revealed that one of the Paris gunmen, Amedy Coulibaly, had visited Madrid days before the attacks.
