The White House has given the go-ahead for the sale of military planes to Nigeria to aid in the fight against Boko Haram, the AP news agency is reporting.
President Donald Trump told President Muhammadu Buhari in a phone conversation in February that he backed the deal.
The deal, said to be worth up to $600m (£490m), was agreed by the Obama administration, but was reportedly halted on the day it was due to be sent to Congress, after a catastrophic incident involving the Nigerian military.
About 90 people, mainly women and children, were killed in January when the Nigerian Air Force mistakenly bombed a camp in the north-east, which was hosting thousands of those who had fled Boko Haram. AFP now says President Trump had approved sales.
