Military fighter jets dropped bombs on the insurgents, halting the attacks after nine hours, said Enoch Mark, a Christian priest in Chibok, some 11 kilometres from the attacked villages.
"We have picked up 10 corpses with bullet wounds" in the bush outside the villages of Kwaranglum and Tsaha, he said.
The gunmen dressed as soldiers stormed the villages early today, razing them and shooting residents as they tried to flee, Mark said.
The schoolgirls' abduction from their dormitory triggered global condemnation.
The gunmen, aboard all-terrain vehicles and motorcycles, arrived in Kwaranglum around 7:00 am (local time), firing indiscriminately and torching homes, according to resident Daniel Haruna, who fled to Chibok.
The attacks were in apparent reprisals for the killing of eight Boko Haram fighters by a local vigilante in Kwaranglum on Tuesday, Haruna said.
