Escape tunnel found at Australian detention centre


A 20m-long (65ft) underground escape tunnel has been discovered at an immigration detention centre in Australia, refugee campaigners say.


The tunnel, at the Yongah Hill detention centre near Perth, was reportedly within five metres of the site's perimeter when it was found.


More than 300 people, including asylum seekers and criminals facing deportation, are living at the site.


Immigration officials have not yet commented on the reports.


The tunnel, said to be three metres deep, led from a room in one of the accommodation blocks and went past two inner fences, towards the outer fence, said the campaign group Refugee Action Coalition.
