Five Nigerian soldiers and more than 15 Boko Haram fighters were killed when the terrorist attacked an army base in the remote northeast where the group has been fighting for an Islamic state, a military source said on Sunday, Reuters reported.
Boko Haram attacked an army brigade in Buni Yadi in Yobe state late on Saturday, an army spokesman said by text message, without giving a casualty figure.
"Five soldiers lost their life in the attack though more than 15 Boko Haram were killed by troops," the military source said.
