A Nigerian military official says public schools are reopening in Borno state, in the country's northeast, where the military has pushed Boko Haram extremists from many cities and towns.

Many schools have been closed for more than two years in areas of the state that had been controlled by Boko Haram, which means "Western education is sinful." A three-month multinational offensive earlier this year drove Boko Haram out of towns including Gwoza which had been headquarters of the group's Islamic Caliphate.

Nigeria's military reopened a public school in Gwoza, Saturday. Military spokesman Col. Sani Kukasheka Usman said schools are being reopened while troops continue to recapture territory from the insurgents. The U.N. children's agency says at least 1.4 million children are currently displaced by Boko Haram's uprising.
