The Nigerian government on Tuesday ordered a probe after an army drone strike accident killed at least 85 civilians last weekend in a village in northwest Kaduna State, emergency officials said.

President Bola Ahmed Tinubu ordered the investigation into one of the country's deadliest military bombing accidents after the army acknowledged one of its drones accidentally struck Tudun Biri village as residents were celebrating an Islamic festival.

The army did not give any casualty figures, but the local residents had said 85 people, many of them women and children, had been killed.

"The Northwest Zonal Office has received details from the local authorities that 85 dead bodies have so far been buried while a search is still ongoing," National Emergency Management Agency (NEMA) said in a statement.

NEMA said another 66 people were being treated at the hospital, but emergency officials were still negotiating with community leaders to calm tensions to be able to reach the village.

"President Tinubu describes the incident as very unfortunate, disturbing, and painful, expressing indignation and grief over the tragic loss of Nigerian lives," the presidency said in a statement.

Nigeria's armed forces often rely on air strikes in their battle against so-called bandit militias in the northwest and northeast of the country, where jihadists have been fighting for more than a decade.
