It was not immediately known if there were casualties.
According to residents, around 50 gunmen in cars and on motorcycles carried out the attacks on three churches and border posts with neighbouring Cameroon, opening fire on police and chanting Allahu Akbar, (God is Greatest).
Among the security posts burned were offices for immigration, customs and the secret police and a quarantine building in the city of Gamboru Ngala, about 140 kilometres (80 miles) from the Boko Haram stronghold in Maiduguri.
“The gunmen believed to be Boko Haram were around 50 in number and came in cars and on motorcyles around 8:30 am and attacked the security offices at the border posts, burning them,” resident Modugana Ibrahim told AFP.
“They opened fire on the security personnel but it is hard to say if anybody was hurt or killed,” Ibrahim said.
Another resident, Hamidu Ahmad, said the gunmen went into town “chanting ‘Allahu Akbar’ and burnt down the divisional police station and three churches”.
