On board an RAF spy-plane sortie over Libya

Nato says it has carried out over six thousand sorties over Libya since the bombing campaign began nearly two months ago.

But how do Nato commanders choose the targets?

The BBC's Caroline Wyatt is the first broadcast journalist to be allowed on board a British spy-plane over Libya.

She reports from RAF Akrotiri in Cyprus, where the air crew has asked that only their first names be used.
