Tornado Gr4

Hello,

Does the Tornado GR4 have a nuclear strike capability, if so what type of weapon can it carry?

Am I right in saying the GR.4 is capable of using the B.61 nuclear free fall weapon. Also is the Storm Shadow able to deliver a nuclear warhead.

I am just curious about how the UK would react against a nuclear attack either from terrorist groups or rogue states. Is there any country capable of launching an air strike against the Europe?
