Visitors to a popular beach may have been exposed to mustard gas, say health chiefs in Wales.
A shell was disabled at Whiteford Sands in north Gower, near Swansea, by Army bomb disposal experts on Thursday.
Two members of the disposal team were later treated in hospital after developing symptoms consistent with potential exposure to mustard gas.
Visitors to the beach between 24 and 28 September who develop symptoms are urged to seek medical advice
