Buhari said this in a statement on Wednesday evening made available to Concise News.
The Nigerian leader also said that international investigation is required and that those behind this horrendous attack must be brought to justice.
He said, “The airstrike on a migrant centre near Tripoli, Libya, is inhuman, wicked and callous. An international investigation is required; those behind this horrendous attack on helpless and defenceless people must be brought to justice.”
Nearly 40 migrants were killed in an airstrike Tuesday night on their detention centre in a Tripoli suburb blamed on Libyan strongman Khalifa Haftar, who has been trying for three months to seize the capital.
At least 70 were also wounded in the raid on Tajoura, an emergency services spokesman told AFP.
