KEBBI, Nigeria — One of 25 schoolgirls abducted from a school dormitory in northwestern Nigeria’s Kebbi state has escaped captivity and returned home, the school principal told The Associated Press on Tuesday.

The girls were abducted when gunmen attacked a high school in northwestern Nigeria before dawn on Monday, taking the 25 girls and killing at a staff member at the school.

The student who escaped fled forests and arrived home late Monday, hours after the kidnapping at the Government Girls Comprehensive Secondary School, said Musa Rabi Magaji, the school principal.

One other student, who was not among the 25 confirmed abducted, also escaped in the minutes that followed the attack, the principal told the AP.
