A huge unexploded World War Two bomb was discovered in central London’s Hyde Park, prompting an evacuation of the area. Specialist officers are currently at the scene close to Serpentine Road.
Both the north and south bank of the Serpentine, a lake within Hyde Park close to Kensington Palace, have been closed, due to “the discovery of suspected WW2ordnance,” said police.
