A WWII German bomb, found in Portsmouth Harbour is to be destroyed.

A 500-metre cordon is in place around the barge as a precaution. As a result cross-channel ferries can't currently leave or enter Portsmouth continental ferry port.
Plans are in place to move the device to allow the ferries access to the port.
Some Naval Base employees have been moved to buildings outside the cordon. Portsmouth Historic Dockyard is closed all day.
Royal Navy bomb disposal experts have inspected the device and a plan is in place to tow it out of the harbour and destroy it in open waters off the eastern Isle of Wight.
