I don’t know if the first image is a dual explosion or simply bisected by a massive amount of debris ejecting towards the photographer. One of the videos in this thread shows a more ‘side’ angle to the explosion, and you can see a massive plume of debris being fired at nearly sonic speeds towards the city center.
