A big dent created by....snow
 

Kuwait Airways plane damaged by 'sudden impact of snow'

I don't know the cause, but it was definitely not snow, and ice or hail seems equally unlikely.

Either some sort of bird-strike, or structural failure of the nose-cone?

Zooming right in that's the most peculiar damage I've ever seen. As far as I can see, the curled out strip has a smaller curled out strip in it. What is that blue thing?

I can't get the definition needed, but the whole under-area of the nose seems to be discoloured. No blood in the dent.

Lighting artifact.
If you look at the third / last photograph you see what looks like a large reddish stain on the tarmac. Likely not related to the incident, but its diffuse reflection on the white fuselage is what gives the fuselage a reddish tinge in the photograph. Crappy cellphone camera and jpeg compression make it appear even more pronounced especially in the first pic.

It looks like an attachment point for an earth strap to me.

Something mechanical has hit that, punching through it then reversing hastily backwards and away, red-faced and praying CCTV didn't catch it.

I dug around a bit and found this higher resolution image. (Edit - Hmm, perhaps not any more information in it than in the published image?)

Perhaps when the dome was pushed in the pressure pulse blew out the "peeled open" portion that is now sticking out? Perhaps combined with some mechanical injury to something inside?

I thought the continuation of that inner strip into the dark patch was a visual artefact, but no, I guess it could be a conductor attached to the blue device.

I'm not certain about the patterning of the red. That too could be camera induced, but having experienced one of the strangest set of (repeatable) patterns created naturally when grinding, I know anything's possible.
