Passenger video screened here shows that there was minor wing and fuselage damage. It also shows fuel leaking from under the wing - but perhaps that was just the fuel dump - I don't know where the dump vents are.
Apparently the reason from the water spraying was that one engine would not shut down - they didn't say which one, but the footage I saw seems to imply that it was the damaged one. There was supposedly also a small fuel leak as well.
