There are tensions between India and Pakistan. People fear they will go to war. Pakistan shot down two Indian fighter jets and captured an Indian fighter pilot. This happened after Indian jets bombed Pakistan. India said it was bombing terrorists. It said the terrorists killed at least 40 Indian police officers in a car bombing.
Pakistan has closed its airspace. Airlines stopped flying over Pakistan and some parts of India. Airlines changed routes to avoid the region. Over 800 flights a day use the India-Pakistan air route. Most flights going to Bangkok and Singapore now have to fly over Iran. They might have to take a detour.
