Soldiers kill Guinea-Bissau president to avenge death of army chief

Renegade soldiers have killed Guinea-Bissau President Joao Bernardo Vieira, hours after a bomb blast took the life of his rival, the armed forces chief of the fragile West African nation, officials said. Luis Sanca, security adviser to Prime Minister Carlos Gomes Jr., confirmed the president's death but gave no details. Gunfire was heard for several hours around Guinea-Bissau's presidential palace early Monday, but the violence died down shortly after dawn. It was not immediately clear whether a coup was under way, and the capital, Bissau, was tense but calm.
