A local living nearby said their house shook following the blast.

This happened shortly after the announcement was made that the final phase of the delicate operation to disarm the bomb was underway.

After reinforcing the blast barrier surrounding the bomb, army specialists revised the original plan to cut the bomb.

They were using a tried and tested approach in order to bring this incident to a safe conclusion.

Norfolk Constabulary's assistant chief constable Nick Davison and strategic co-ordinating group chair said: “As previously stated, there was always a risk of unintended detonation which is why those mitigation measures had been put in place throughout the operation.

“The device detonated shortly after work had started to disarm the device. The approach had been the safest option to disarm the device, however, it always carried a risk of unintended detonation.

“Thankfully, all personnel have been accounted for and agencies are coming together to assess damage to the river wall.”
