Former naval head Admiral Jose Americo Bubo Na Tchuto and two aides have been detained in connection with the attempted coup, according to President Umaro Embalo.
While Embalo was chairing a cabinet meeting in Bissau, heavily armed men stormed government buildings. Embalo, 49, subsequently informed reporters that he had fled the five-hour gun war unscathed and that 11 people had died in the conflict.
He listed retired rear admiral Jose Americo Bubo Na Tchuto, who led the navy in the early 2000s, as one of three persons detained in connection with the attack on Thursday.
Tchamy Yala, another former cop, and Papis Djeme were the other two, he added, and all three had been detained. The attack on government facilities was related to the transatlantic drug trafficking, according to Embalo.
