UPDATE: 7 children killed, 4 NEMA staffers, 16 others injured in Adamawa IDP camp bombing

At least seven children have been confirmed killed in a bomb explosion at an internally displaced persons (IDP) camp in Adamawa State, north-eastern Nigeria.

Official sources say 20 people were injured in the attack.

The National Emergency Management Agency (NEMA) said four of its staffs were among the 20 already confirmed injured in the blast which occurred at about 10:50 a.m.

Seven of the injured have been discharged from hospital.

NEMA said the remaining thirteen, four of them its staffs, were receiving treatment in hospital.

The agency said the bomb went off inside a tent in Malkohi IDP camp in Yola, Adamawa State.

There are at least 1200 IDPs at the camp, many of them children.

Reports say security and rescue agencies are evacuating IDPs from the camp.

NEMA earlier confirmed the attack in a tweet it later deleted.

The bombing was then confirmed by Adamawa State Governor Umaru Bindo.

Bindo confirmed the news to a group of northern state governors on Friday afternoon.

“The Governor of Adamawa just informed the Northern States Governors’ Forum that an explosion took place in an IDP camp in Yola killing seven children and injuring ten persons,” Kaduna State Governor Nasir El-Rufai, a member of that group, posted on Facebook.

NEMA has now reviewed the injury toll to 20.

The attack comes on a day the Bring Back Our Girls Group, an advocacy movement seeking the rescue of schoolgirls Boko Haram kidnapped from Chibok in April 2014, celebrated its 500 days in existence.

Boko Haram is the prime suspect, as usual, for the camp attack on children who became IDPs as a result of the terror the Islamic extremists are unleashing on Nigeria’s north-east.

The sect, whose claim to Islam has been summarily dismissed, has killed at least 800 people since President Muhammadu Buhari was sworn in on May 29.

Boko Haram’s activities have also displaced over two million Nigerians from their homes, taking the number of Nigeria’s IDPs beyond the three million mark – the highest figure in Africa.

Nigeria’s IDPs are sheltered in various camps managed by NEMA.
