Gunmen believed to be Boko Haram militants have shot dead dozens of people in a northeastern Nigerian village -- the fourth such massacre reported this week.
A local source tells VOA Hausa Service that men wearing military uniforms entered the Borno State village of Bardari and asked people to come listen to a preacher. The source says when the villagers gathered, the men opened fire.
Suspected militants using similar tactics attacked three other villages Monday and Tuesday in the nearby Gwoza district. Witnesses and officials say the militants killed hundreds of people in those attacks and burned down many homes and businesses.
More attacks were reported Thursday in two towns of neighboring Adamawa state -- Madagali and wa Kubla.
The Nigerian government has struggled to contain Boko Haram despite a state of emergency in the northeast and deployment of thousands of troops to the area.
