LAGOS, Nigeria (CNN) -- Stella Obasanjo, wife of Nigerian President Olusegun Obasanjo, died Sunday at a hospital in Spain, officials said.
She had traveled to Spain to undergo surgery and died from complications resulting from that surgery, authorities said.
Stella Obasanjo, 60, was hailed as Obasanjo's "beloved wife," according to a one-sentence statement signed by presidential spokeswoman Remi Oyo, The Associated Press reported.
The Spanish Foreign Ministry said Obasanjo's wife died Sunday morning at a hospital in the southern resort city of Marbella, where she had been on a private visit.
The ministry said it had no information on the cause of death, and that the body was taken to a coroner's office in nearby Malaga for an autopsy.
