Yeah, all the post WW2 nuclear weapon uses follow that MO, with an initial conventional weapons to set off a conflagration, and then the nuke to obliterate the target.

Unfortunately the video of that Sudan explosion starts just after the initial blast.

We know what a nuclear explosion looks and sounds like (https://www.youtube.com/watch?v=Mn7PeI2UyEM). The key distinguishing characteristic is that the intense flash of light, and the pressure wave are a dirac delta function, all the energy of the explosion is released in a microsecond, faster than a detonation can travel through high explosives.

Check out this nuking of a port in Iran. The flash is bright as the sun and lasts a single frame. That's not rocket propellent cooking off like they say, rocket fuel doesn't even detonate, it deflagrates.
