ABUJA, Feb. 25 (Xinhua) -- The Nigerian military on Sunday said it had deployed air assets, including intelligence, surveillance and reconnaissance platforms, in search of the scores of missing schoolgirls in the country's northeast region.

Air force spokesman Olatokunbo Adesanya said air operations in search of the girls are being conducted day and night.

Terror group Boko Haram is suspected to have abducted the girls, following an attack on the Government Girls Technical College in Dapchi area of the northeastern state of Yobe last Monday.

The Nigerian government on Sunday said 110 schoolgirls are unaccounted for following the attack.

"It is noteworthy that the renewed efforts at locating the girls are being conducted in close liaison with other security forces," Adesanya said.

A government spokesman said no stone will be left unturned as the government is determined to rescue every missing student.

In a statement on Friday, Nigerian leader Muhammadu Buhari described the incident as a "national disaster," saying "the entire country stands as one with the girls' families."

Buhari had also vowed to rescue the schoolgirls by sending more troops and surveillance aircraft to search for them.

The tragedy of the missing girls has brought back memories of a similar occurrence four years ago in Africa's most populous country when more than 200 schoolgirls, also from an all-girl college, were abducted by Boko Haram in the northeastern town of Chibok.

The outlawed Boko Haram group has been trying since 2009 to establish an Islamic state in northeastern Nigeria. They have killed some 20,000 people and displaced millions of others.
