“We have decided, after having taken the president, to dissolve the constitution,” said a uniformed officer flanked by soldiers toting assault rifles in a video sent to AFP.
The officer also said that Guinea’s land and air borders have been shut and the government has been dissolved.
Another video sent to AFP by the putschists showed a rumpled-looking President Alpha Conde sitting on a sofa, surrounded by troops. He refused to answer a question from one soldier about whether he was being mistreated.
Guinea — one of the world’s poorest countries despite boasting significant mineral resources — has long been beset by political instability.
Earlier on Sunday, residents of the capital Conakry’s Kaloum district, the government quarter, reported hearing heavy gunfire.
A Western diplomat in Conakry who declined to be named suggested the unrest may have started after the dismissal of a senior commander in the special forces — provoking some of its highly trained members to rebel.
AFP was unable to independently confirm this account.
