The number of people mistakenly killed last week in an air attack on a camp for those who have fled conflict in north-east Nigeria has risen to 236, an emergency official has told the BBC.
Camp residents and aid workers were among those killed when the air force bombed Rann, in Borno state, thinking it was a base of Boko Haram militants.
It was the biggest known botched attack in eight years of fighting the group.
The military has said it is engaged in a “final push” against the Islamists.
Commanders have apologised for the “accidental” bombing, which they said was because of “the fog of war”.
Human Rights Watch said this did not absolve them of responsibility, and called for compensation for the victims.
An aid worker told the BBC that the attack, in which at least two bombs were dropped, caused terror and chaos at the camp.
He said he saw dead children lying on the ground, others left as orphans and terrible injuries among survivors.
Aid workers estimated 20,000-40,000 people had been sheltering in Rann, near the border with Cameroon, after fleeing attacks by Boko Haram.
