ANGOLAN authorities on Monday introduced journalists to a young man purporting to be a son of Unita leader Jonas Savimbi with whom he has fallen out. “I am in disagreement with him,” said Araujo Domingos Sakaika (22) who bears an Ivorian passport. Sakaika said he left the central Unita stronghold of Andulo, which fell last month to government forces, in August 1997 for Abidjan via Libreville. He then went to Lome for literature studies, he said. Savimbi has “at least five sons in Lome and five in Paris, where they are studying,” Sakaika said. The young man did not say when he arrived in Luanda, and his passport bore no stamp by Angolan immigration authorities.
