The security official, who sought anonymity as he was not authorised to speak, also denied the rumor that some of the girls were rescued on Saturday.
He, however, said there were high hopes for the quick rescue of the girls based on the ongoing cooperation between Nigerian officials and their counterparts from the U.S. and U.K. on the rescue efforts.
"It is not true that they have been rescued yet, but we noticed and observed movement of some of the girls from the Sambisa region towards Ashaka forest in Gombe state", said the security personnel.
The officer added that efforts are being put in place to "carefully track" the abductors and get the girls freed.
