Soon after the latest crash, Nigeria's president suffered another blow when his wife, Stella, died in Spain. She would have been 60 next month.
In a one-sentence statement signed by the presidential spokeswoman, Remi Oyo, described her as Obasanjo's "beloved wife." No further details were given as to what caused her death.
The Spanish Foreign Ministry said she died Sunday morning at a hospital in the southern resort city of Marbella, where she was on a private visit. It had no information on the cause of death and did not know if she had undergone surgery, as asserted by Nigerian officials in Abuja.
The body was taken to a coroner's office in nearby Malaga for an autopsy, the ministry said.
