An Iranian woman is among around two dozen migrants set to arrive in the Central African Republic on a deportation flight from the United States, lawyers said.
The Central African Republic, a deeply impoverished country plagued by conflict, is one of at least nine other African nations that has agreed to take third-country deportees.
The Trump administration has deported thousands of people to nearly two dozen countries that are not their own, advocates say.
Among those set to be deported were people from Iran, Jordan, Armenia, Turkey, Georgia and Afghanistan.
Three Iranian women in the US were originally scheduled to be sent to Central African Republic, but two of them received emergency court orders temporarily stopping their deportation.
The Central African Republic has been plagued by years of conflict between pro-government forces and armed groups and is one of the poorest countries in the world.
Russia's influence in the country and Moscow's close security ties with Iran have raised concerns among advocates.
