BAUCHI, Nigeria (REUTERS) - Suspected members of Islamist militant group Boko Haram took over a town in the restive state of Borno in north-east Nigeria on Saturday (Nov 25), residents said.

The attack comes days after a suicide bomber killed at least 50 people at a mosque in neighbouring Adamawa state in one of the deadliest attacks since President Muhammadu Buhari came to power in 2015 pledging to end the eight-year insurgency.

Residents said attackers entered Magumeri, around 50km from Borno state capital Maiduguri, around 7pm (2am on Sunday, Singapore time). They said the insurgents shot sporadically and threw explosive devices, prompting locals to flee to a forest.

"We hurriedly took our families to the bushes before they could get us. Almost every resident is hiding here," said Wakil Bulama, one of two residents who spoke to Reuters by telephone.

A military source who did not want to be identified said Magumeri had been attacked but could not confirm whether it had been seized.

Boko Haram has waged an insurgency in northeastern Nigeria since 2009 in its attempt to create an Islamic state in the region. The group has killed more than 20,000 and forced around two million people to flee their homes.
