American officials believe that new satellite photographs of North Korea show intensive preparations for a possible nuclear weapons test, it was reported yesterday.

The imagery is said to show tunnels being dug under a mountain in the north-east of the country and then rock and building materials being taken back in, possibly in an effort to contain an underground blast.

The pictures also show what appears to be an observation stand a few miles away.
