PARIS (AFP/Reuters) - Documents threatening France with attacks were found at the base where US soldiers killed Osama bin Laden, a French intelligence source told AFP late Friday. "Yes, we received documents from our American friends," the source said, confirming earlier reports in Paris Match magazine and on France Info radio. But he added that the documents were more expressions of intent than fully formed plans and needed to be seen in that context. US Navy Seals seized the information during the May 2 operation in which they killed the leader of Al-Qaeda at a compound in Pakistan, ending one of the most high-profile manhunts in history. While the documents certainly contained threats against France, they were "disjointed and... to be handled with caution," said the intelligence source. They were more of a commentary than fatwa, or religious edict, the source added. France's internal and foreign intelligence services, the DCRI and DGSE, refused to comment on the matter. Bin Laden made several threats against France, the last one coming in an audio-taped message issued in January 2011. In June, following the raid, US President Barack Obama said that the documents recovered from the raid showed that the Al-Qaeda network was under "enormous strain." Meanwhile, France Info radio said on its website that Osama wanted al Qaeda hostage takers to use their French captives to discredit President Sarkozy and his security policy ahead of a presidential election next year, possibly by killing them . The news radio channel, said bin Laden had issued written instructions to members of al Qaeda's north African offshoot, known as AQIM, on how to handle a group of hostages, including five French nationals, captured in Niger last year.
