The US Federal Aviation Administration closed the airspace around the border city of El Paso, Texas, for 10 days, in an unusual move that authorities put down to unspecified “special security reasons.” All flights into and out of the city are suspended, the FAA said without elaborating on the reasons. The FAA has also prohibited all flight operations in the Santa Teresa area of New Mexico, citing special security reasons.  Flights from El Paso International Airport were halted starting Feb. 10 at 11:30 p.m. local time and will stay suspended until the same time on Feb. 20, the airport operator said in a travel advisory posted on its official Facebook and Instagram accounts.
