The Police have arrested a dozen people suspected of helping the Islamist militant gunmen in last week’s Paris killings, the city prosecutor’s office said on Friday as U.S. Secretary of State, John Kerry, arrived for talks.
They are being questioned about “possible logistical support”, such as weapons or vehicles, they could have given the three gunmen, police say.
Raids were still taking place in Montrouge just outside Paris, where gunman, Amedy Coulibaly, killed a policewoman last week.
Paris police evacuated the Gare de l’Est train station on Friday after a bomb threat, as authorities across Europe pressed on with efforts to prevent new violence after one of the worst attacks in decades.
Similar anti-terrorism raids and arrests took place in Belgium and Germany.
According to police source, investigators have followed several people over the past few days that had been pinpointed thanks to probes on people in the alleged entourage of the Kouachi brothers, who waged the Charlie Hebdo attack, and Coulibaly, who killed a policewoman and four people in a kosher supermarket.
French authorities say that about 120,000 police and soldiers are now mobilised across France and that anti-terror plans remain in place.
Prime Minister, Manuel Valls, said on Friday that France and Belgium were facing the same threats, but added that there were no links between the events in France and Belgium’s anti-terror raid on Thursday.
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.
