The French government said Wednesday officials are working to verify the authenticity and date of new online video showing four French hostages held by al-Qaida's north Africa branch. SITE Intelligence Group, a U.S.-based tracker of extremist websites, says the 3 1/2-minute video was posted on jihadist forums on Tuesday. There has been very little sign of life from the hostages since they were kidnapped in September 2010 in Niger. Al-Qaida in the Islamic Maghreb claimed responsibility for the kidnapping seven hostages including Pierre Legrand.
