FAA has told US carriers (like everyone all US carriers. Not just civil aviation) not to fly below FL260 in Afghanistan airspace. They stated that they were doing this because of extremist activity. Probably best they do to keep everyone safe
It’s definitely good idea because if the enemy’s radar ever detected the aircraft, they can fire the missiles at the commercial airliner so it’s best to fly higher for safety precautions
"Taliban forces intend to retaliate to the announcement that the withdrawal of US forces will be gradual, not immediate – as they believe this violates existing agreements. This has increased the risk to civil aviation. The Taliban have previously attacked aviation interests by a variety of means…”
Afghanistan was better for a while when the US and other foreign armies occupied it. It will be getting worse since there’s only the government forces left to fight the Taliban extremists…
It has an international impact since it doesn’t only affect the local population, but literally every plane which uses its airspace.
