Hovertravel services remain suspended this afternoon (Tuesday) after a piece of unexploded ordnance was discovered earlier today.
Police remain on scene on the seafront in Southsea following the discovery at around 9.35am.
It is reported that a suspected WWII bomb was discovered by diggers carrying out sea defence works.
Cordons have been put in place and premises within that area have been evacuated for their safety.
These include Blue Reef Aquarium, the D-Day Museum, Clarence Pier and parts of the common.
No residential properties have been evacuated.
A spokesperson for Hampshire and Isle of Wight Constabulary said:

"We will issue an update once the cordons have been lifted."
