"The two sides apparently agreed to a 'deconfliction mechanism' in which operations at the airport in Kabul are permitted to continue without interference from the Taliban."

Reports The Hill in "US reaches deal with Taliban on evacuations: report." 

I'd never noticed the word "deconfliction" before, but the OED traces it back to 1973, and defines it as "To reduce the risk of collision in (a combat situation, airspace, etc.) by separating the flight paths of one's own aircraft or airborne weaponry." Example (from Time, 1974): "What the brass calls ‘deconfliction’—making sure warplanes and relief planes don't confuse one another—is now a major focus of the Pentagon strategy."
