A shadowy Islamist insurgency that has haunted northern Nigeria \u201d\u201d surviving repeated, bloody efforts to eliminate it \u201d\u201d appears to be branching out and collaborating with Al Qaeda\u2019s affiliates, alarming Western officials and analysts who had previously viewed the militants here as a largely isolated, if deadly, menace.<\/p>\n
Just two years ago, the Islamist group stalking police officers in this bustling city seemed on the verge of extinction. In a heavy-handed assault, Nigerian soldiers shelled its headquarters and killed its leader, leaving a grisly tableau of charred ruins, hundreds dead and outmatched members of the group, known as Boko Haram, struggling to fight back, sometimes with little more than bows and arrows.<\/p>\n
Now, insurgents strike at the Nigerian military, the police and opponents of Islamic law in near-daily assaults and bombings, using improvised explosive devices that can be detonated remotely and bear the hallmarks of Al Qaeda in the Islamic Maghreb, Western officials and analysts say. Beyond the immediate devastation, the fear is that extremists bent on jihad are spreading their reach across the continent and planting roots in a major, Western-allied state that had not been seen as a hotbed of global terrorism.<\/p>\n
