Boko Haram Islamic extremists struck the northeast Nigerian city of Maiduguri for the first time in months Monday with rocket-propelled grenades and multiple suicide bombers, witnesses said.<br />Maiduguri, the city under attack, is the birthplace of Boko Haram, which emerged as a much more radical entity after Nigerian security forces attacked their compound there, killing 700 people in 2009.<br />Militants firing indiscriminately from the back of three trucks attacked the outlying village of Dawari, soldiers engaged them, and as people were fleeing, a woman ran into a suburb yelling "Boko Haram, Boko Haram."<br />The attack comes as Nigeria's government says it has contained the Islamic uprising that has killed 20,000 people in six years and driven 2.3 million people from their homes.
