Runways don't burn, but fuel spilled on runways can burn, and that fire looks exactly right in the darkness to be that.
Notice the flames close to the ground and how it changes color a bit further up, and color of the smoke. They are all the correct colors for it to be aircraft fuel on fire on a flat runway surface.
At minimum they destroyed fuel tankers that fill the air craft. Or they destroyed the aircraft and that spilled fuel out of their tanks onto the runway. Or both.
