The first attack on Monday afternoon killed 10 in the village of Shawa, some seven kilometers from Chibok, a number of residents told AFP on condition of anonymity.

Gunmen then stormed the nearby village of Alagarno late on Tuesday and stole food, razed homes and fired on fleeing civilians. "It was a sudden attack," said resident Haruna Bitrus, in an account supported by other locals.

"They began shooting and set fire to our homes. We had to flee to the bush. They killed 20 of our people," he added.
