Kano (Nigeria) (AFP) - Boko Haram's leader said in a video obtained by AFP on Thursday that the group was behind a daring raid on military installations in the north Nigerian city of Maiduguri earlier this month. "Allah the Almighty has given us victory in the attack we launched inside Maiduguri (which was) called Borno in ancient times," said Abubakar Shekau in a 40-minute clip. Speaking in Arabic, Hausa and Kanuri widely spoken in northeast Nigeria, Shekau added: "We stormed the city and fought them (and) Allah blessed us with lots of booty." He speaks for 19 minutes in all while the rest of the tape shows images of burning buildings and aircraft said to be from the December 2 attack in Maiduguri, which is capital of Borno state.
