In a statement on Tuesday, spokesman Colonel Onyema Nwackukwu said the offensives took place in border villages of Kusha-Kucha, Surdewala, Alkanerik, Magdewerne and Mayen, culminating in the destruction of several Boko Haram camps and seizure of weapons, including machine guns and anti-aircraft guns.
Four improvised explosive devices were also destroyed.
Nwackukwu said some 603 hostages were freed across Kusha-Kucha, Surdewala, Alkanerik, Magdewerne and Mayen villages; they were taken to the Nigerian Bama town for profiling and handing over to relief agencies.
"The troops also extracted 194 civilians held captive by the insurgents and destroyed makeshift accommodations erected by the insurgents. Additionally, the combined troops successfully cleared Miyanti and Wudila villages, where they rescued three men, 121 women and 209 children," the army spokesman added.
On Tuesday, the Organization of Islamic Cooperation (OIC) Secretary-General Dr Yousef Al-Othaimeen condemned the abduction of some 110 schoolgirls from Nigeria’s northeastern Dapchi town Monday.
