Rear Adm. Americo Bubo Na Tehuto allegedly called several other commanders and asked them to join in the overthrow of President Joao Bernardo Vieira, the BBC reports. One of the recipients of his calls was the army chief of staff, who had him placed under house arrest, Col. Arsenio Balde said.
Guinea-Bissau is a small country on the west coast of Africa. Vieira came to power in a military coup in 1980, six years after the country became independent from Portugal, was thrown out in 1999 and won election as president in 2005.
Recently Vieira dissolved parliament after a major party left the unity government.
