Lord Mountbatten and two teenagers were murdered while fishing near Donegal Bay when bomb exploded on their boat.

A young boy who was on the shore just a couple of hundred yards from where the explosion took place describes what he saw.

An elderly farmer, who was bailing hay in the fields describes seeing the boat coming out of the harbour and hearing a loud explosion. 

I seen the smoke and debris going up... When the dust went away, there was nothing there.
