Paris terror attack investigation follows the gun, money trail

Описание: UNDATED (CBS News) -- Nearly a week after the start of a three-day wave of deadly terror attacks in France, authorities revealed new details about the weapons used in the attacks and how the gunmen were financed.

The search continued for at least six members of a suspected terror cell linked to the men who carried out the massacre which initiated the three-day nightmare. Seventeen people were killed, including 12 in an attack on satirical newspaper Charlie Hebdo's Paris office.

French police believe the brothers who carried out the Charlie Hebdo attack on Wednesday and were killed two days later in a raid on a business northeast of Paris, were part of a cell of eight to 10 people with possible links to al Qaeda in the Arabian Peninsula.

The French-Algerian brothers, Said and Cherif Kouachi, said they were members of the al Qaeda affiliate, based in Yemen, and the group released a video statement after the attacks claiming responsibility.

CBS News has learned that Said Kouachi returned from Yemen in 2011 with $20,000 from AQAP to finance the operation in Paris.

The weapons used by a terror cell to kill 17 people around Paris came from outside the country and authorities are urgently tracing the source of the financing, a French police official said Tuesday.

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.

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.
