Input: Kano, Nigeria (CNN) -- The fight against militant Islamists in Nigeria led to dozens of deaths, mostly of civilians, in three villages this weekend. A military plane trying to bomb camps of the Boko Haram extremist group in the Sambisa Forest on Friday night "mistook the village (Daglun) for a Boko Haram camp," said Ali Ndume, a senator representing the region. The inaccurate air raid was part of "an ongoing offensive" against the insurgents, Ndume said. Ndume said the four bombs dropped by the government aircraft killed five people and wounded several others. But Daglun residents, some of whom were forced to flee into the bush from burning homes, said the bombardment caused many more casualties.NEW: Military denies reports that civilians were mistakenly killed in air operationsOn Saturday, attackers destroyed Mainok village in Nigeria, killing 39 peopleResidents blame Boko Haram for the rifles-and-grenades assaultIn another town, two explosions about two minutes apart killed dozens, residents say
