I just learned about this.
The U.S. military is unable to fly drones from a base in Niger because the country’s airspace has been closed after a coup overthrew the government in late July, a U.S. official said.
Known as “Nigerien Air Base 201,” the installation cost $110 million to build and it features a 6,200-foot runway for MQ-9 Reapers as well as manned aircraft. The U.S. military began conducting drone flights from the base in November 2019.
About 1,100 U.S. troops are currently deployed to Niger, according to the Defense Department. The country is an important partner in the U.S. military’s efforts to counter the Islamic State group and other terrorist organizations in Africa

US troops in Niger have been restricted to the American military bases and US embassy in Niger, as the Biden administration works to restore democratically-elected President Mohamed Bazoum to power.
A US military official said the approximately 1,000 troops were “retrograded” back to base last week, shortly after Bazoum was seized by members of the presidential guard on Wednesday. Another US official confirmed the troops are restricted to the bases and the embassy, but said all of the forces were already at their respective stations when the attempted coup occurred.
