In this image taken from video and released by SITE Intelligence Group on Wednesday April 27, 2011, shows hostage French Daniel Larribe. 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 Daniel Larribe.
