Three tanks and dozens of armed soldiers are heading toward Guinea's presidential compound.
An Associated Press reporter saw the troops and tanks moving in the direction of the compound, which houses the office of the West African nation's prime minister.
The troops' allegiance was not immediately apparent, reported AP.
But they appeared less than an hour after Prime Minister Ahmed Tidiane Souare announced in a state broadcast that he was inside his office and that his government had not been dissolved.
Junior army officers had announced a coup d'etat earlier Tuesday. They said the government had been dissolved hours after the death of longtime dictator Lansana Conte was announced.
