France Considers Tightening Surveillance

PARIS (AP) -- France will seek tighter surveillance of convicted extremists, the country's prime minister announced Tuesday as reports emerged that the arsenal of weapons used by a terror cell to kill 17 people around Paris came from abroad.

In a rousing, indignant speech, Prime Minister Manuel Valls said "serious and very high risks remain" and warned the French not to let down their guard. He called for new surveillance of imprisoned radicals and told the interior minister to come up with new security proposals shortly.

Several people are being sought in relation to the "substantial" financing of the three gunmen behind the terror campaign, said Christophe Crepin, a French police union official. The gunmen's weapons stockpile came from abroad, and the size of it plus the military sophistication of the attacks indicated an organized terror network, he added.

"This cell did not include just those three, we think with all seriousness that they had accomplices, because of the weaponry, the logistics and the costs of it," Crepin said. "These are heavy weapons. When I talk about things like a rocket launcher - it's not like buying a baguette on the corner, it's for targeted acts."

French police say as many as six members of the terrorist cell that carried out the Paris attacks may still be at large, including a man seen driving a car registered to the widow of one of the gunmen. The country has deployed 10,000 troops to protect sensitive sites, including Jewish schools and synagogues, mosques and travel hubs.
