A grab made on May 5, 2014 from a video obtained by AFP shows the leader of the Islamist extremist group Boko Haram Abubakar Shekau delivering a speech.
An attack by Boko Haram Islamists in a northeastern Nigerian town on the Cameroon border has killed hundreds of people, a local senator and witnesses said on Wednesday.
News of the gruesome attack in Gamboru Ngala emerged hours after Islamists stormed the town on Monday, but casualty figures had remained unclear.
Area senator Ahmed Zanna told AFP that "the death toll from the attack is around 300," while residents said more than 100 bodies had been collected so far and that the toll was likely rise.
