Authorities in France say the weapons used in the recent terror attacks came from outside of the country. These incidents, including the Charlie Hebdo shooting, left 17 people dead last week.

A source with French police told the Associated Press that authorities have focused their efforts on determining who financed the weapons: 

Christophe Crepin, a French police union representative, said several people were being sought in relation to the substantial financing of the three gunmen, as well as others in their network. He said the weapons stockpile clearly came from abroad and the amount spent shows an organized network.

During a speech today, French  Prime Minister Manuel Valls called for tighter security measures as France works to protect itself from future attacks.
