A million children on the run from Boko Haram, says Unicef.
ATTACKS by armed extremist group Boko Haram have forced 500,000 children to flee their homes in the last five months, according to Unicef.
The UN children's agency says 1.4 million children overall are "on the run" in Nigeria and neighbouring countries where the group has sown terror in recent months.
More than half of the 1.2 million children who have fled northern Nigeria are aged under five.
Spokesman Christophe Boulierac says Unicef is in "full operational mode" in the region but has received less than a third of the $US50m(PS32m) funding it has sought for the Lake Chad region.
At a UN news conference in Geneva, Mr Boulierac also appealed for renewed attention on the 219 girls abducted in April last year from a school in Chibok, Nigeria.
Earlier this week Nigeria's army said it had rescued at least a dozen kidnapped women and children held captive by tBoko Ha!ram, but they did not include any of the 219 girls.
