Malabo - A plot to abduct the president of the small, oil-rich west African nation of Equatorial Guinea was unveiled on national television on Wednesday by the alleged leader of a group of mercenaries, apparently a 48-year-old South African. Malabo called on Wednesday for the extradition of Moto, who tried to mount a coup against Obiang in 1997 from Angola and recently set up a government in exile in Spain. But Moto denied any involvement in the alleged plot. Severo Moto "has at no time left Spain," said a statement issued by his government in exile. Moto also went on the offensive, telling Spanish radio station Onda Cero that Obiang was an "authentic cannibal" who "systematically eats his political rivals. "A while back he paid millions to those they call marabou (sorcerers) to tell him if his power base was safe. They told him that to keep his grip on power he had to kill people close to him. "Obiang wants me to go back to Guinea and eat my testicles. That's clear," he told Onda Cero.
