Antonio Guterres, United Nations secretary-general, has condemned the military takeover that took place in Guinea on Sunday.
Mamady Doumbouya, head of the elite national army unit, said the president had been taken into custody.
Doumbouya accused Conde’s government of “trampling of the rights of citizens” and disrespecting “democratic principles”.
He also announced that the country’s land borders had been closed and the government dissolved.
Condé was re-elected for a third term in office amid violent protests in October 2020.
The president won the controversial election after changing the constitution to allow him to serve another term in office despite stiff opposition.
Conde’s decision to run for a third term had sparked repeated protests that resulted in the deaths of dozens of people.
