Gabon's President Omar Bongo, 73, has died in a hospital in Spain.
After conflicting reports about Bongo's death throughout Monday, Gabon's Prime Minister Jean Eyeghe Ndong has confirmed that Bongo had died, news agencies reported. Bongo reportedly suffered a heart attack.
Bongo was in Spain receiving treatment for cancer. He stepped down from day-to-day activities in early May as a result of his health.
Bongo, one of three African heads-of-state facing a French corruption investigation, was Africa's longest serving ruler. He assumed power in Gabon in 1967.
