An unidentified unexploded bomb has been found at a river bank in west London. The munition was encountered during ground works associated with the Thames Tideway super-sewer.

Chelsea Embankment was temporarily closed as the weapon was removed by a crane. It is unclear what type of bomb this was.

No further details relating to this incident were found. The majority of unexploded German bombs found in London are not reported in the media. Many are the small 1kg type of incendiary bomb which are relatively less hazardous. Consequently, they can be more quickly removed by the army, with disruption caused.

The River Thames is likely littered with German bombs dropped during both WW1 and WW2. Any bomb observed as not detonating when striking the water would not have been recovered.

In 2017, another unexploded German bomb was found in the River Thames, a kilometres downstream of this incident. The device was identified as an SD 50; a semi-armour piecing high explosive bomb.

The subsequent operation by the Royal Navy and Metropolitan Police forced Waterloo Bridge, Westminster Bridge and Victoria Embankment in central London to shut. The WW2 munition was later towed along the river to Tilbury, Essex, where it was safely detonated.

Even the smallest German general purpose high explosive bombs contain a 25kg warhead. A UXO find such as this poses a deadly hazard to site personnel, plant and buildings.
