Over 300 people were killed on Monday in an attack on a small town in northeast Nigeria. In a marked escalation of violence, Islamic militants stormed Gamboro Ngala, a town on the border with Cameroon, firing upon a crowded marketplace and torching many homes and shops. According to the AP, the gunmen descended upon the village in the evening, when cooler temperatures attract large crowds to the market.Nigerians are still reeling from the recent kidnapping of more then 200 schoolgirls by the Islamist group Boko Haram. The group is behind most of the violence that has wracked the country in recent years. President Goodluck Jonathan and his government have been scrambling to keep a lid on the insurgents, who have only grown more bold in recent months. Once confined to the country’s rural northeast, Boko Haram has demonstrated its ability to inflict massive damage in Abuja, the country’s capital. Four days ago the U.S. State Department announced that the group may be planning to attack one of two Sheraton hotels in Lagos, the country’s main commercial hub. The militants have also been keen to disrupt the country’s oil operations, the lifeblood of Nigeria’s economy.Despite Boko Haram’s bloody assaults, Nigeria’s economy recently became the largest in Africa. Yet the economic numbers, impressive as they may be, are no comfort to citizens terrified for their own and their children’s safety.
