UFOs have once again been spotted in the Dales fueling a report that sightings of strange objects are rising.

The Ministry of Defence has revealed its own X-files for 2007, listing 135 sightings - including a mysterious object in Wirkworth.

Clusters of bright white lights, strange, triangular shaped objects and stationary craft in Wirksworth are just some of a huge surge in sightings reported last year.

And it seems the UK is becoming a more popular destination for aliens as sightings have rocketed from 2006 when just 97 were reported.

The Ministry of Defence released the file as part of plans to open its archives on UFO research.

A spokesman said the incidents were recorded but unless some security threat is suspected the Ministry has not investigated the cause of sightings any further.
