CNN reports Boko Haram militants have unleashed another torrent of violence in northeast Nigeria, killing 79 people in three recent attacks there, residents and local militia said. In the first and deadliest attack late Friday, gunmen entered the village of Baanu -- about 50 miles (80 kilometers) north of Maiduguri, the capital of Borno state -- and shot dead 68 people. The gunmen seemingly shot indiscriminately, spurring survivors to run for their lives into the bush, according to residents. The next attack happened around 2 p.m. Saturday in Hambagda village in Borno state's Gwoza district, 80 miles from Maiduguri. Militants, again on horseback, unloaded on worshipers at a mosque -- leaving seven dead and five more wounded, locals and militia leaders said. Another attack about five hours later in in the village of Karnuwa, which is close to Baanu, resulted in the deaths of the village's imam, his son and two neighbors.
