UNICEF says it will not allow the attack on its convoy divert it from reaching the over two million people in need of aid in the north-east.
On Thursday, a humanitarian escort duty and Nigerian soldiers were ambushed and attacked by Boko Haram insurgents in Borno state.
The convoy, which was en route Maiduguri from Bama, included staff from UNICEF, UNFPA, and IOM.
Describing the attack as “heartless”, Jean Gough, UNICEF representative in Nigeria, said the task at hand is important.
