Maiduguri - Military reports and witnesses say hundreds of people have been killed as troops from Chad seized the Nigerian town of Dikwa from Boko Haram extremists while Nigerian soldiers fought off a separate attack miles outside the biggest city in northeastern Nigeria.
Chad spokesperson Colonel Azem Bermandoua said Boko Haram left hundreds of people dead in Dikwa on Monday before fleeing Chadian forces. He said one Chadian soldier was killed and 34 were injured.
The United Nations said 16 000 Nigerians fled the fighting into Cameroon.
