The US is building a military air base in Niger [13] that will be capable of deploying drones to police the greater Sahara and Sahel regions. The US already has a presence [14] in the capital Niamey, where it shares an airbase with with French troops from the anti-Islamist Operation Barkhane [15]. The new facility, in the central city of Agadez, will give Washington greater ability to use drones against Islamist extremists in neighboring Libya, Mali and Nigeria. A Pentagon representative confirmed the US has agreed to pay for a new runway and "associated pavements, facilities and infrastructure," estimating the cost at $50 million. But The Intercept [16], which broke the story, said it is projected to cost twice that. The news site reports that it has obtained files indicating the project is considered "the most important US military construction effort in Africa," and will be completed in 2017.
