Last month's coup in Niger has raised questions over whether the United States can continue the 1,100-strong military presence in the country that officials and analysts say has been key to fighting Islamist militants in the Sahel region.
Over the past decade, U.S. troops have trained Nigerien forces in counterterrorism and operated two military bases, including one that conducts drone missions against the Islamic State and an Al Qaeda affiliate in the region.
After ousting former Nigerien President Mohamed Bazoum from office on July 26 and placing him under house arrest, the junta revoked military cooperation agreements with France, which has between 1,000 and 1,500 troops in the country.
