BBC NEWS | UK | Wales | South West Wales | 'Anthrax bomb' answers demanded
An MP is demanding reassurances that nothing remains of an anthrax bomb tested in a south Wales estuary during World War II.
Llanelli MP Nia Griffith made the call after it emerged the weapon was dropped off the town's coastline.
There have been concerns about water quality and the death of cockles in the Burry estuary.
The Ministry of Defence said there was no contamination following the experiment in 1942.
A spokesman for the MoD said: "The Gower coast was often used for munition testing during WWII.
"However, a bacterial weapon was only tested once, in 1942, when a 30lb bomb charge with anthrax spore was dropped from a Blenheim aircraft at 5000 feet.
"There was no residual contamination of the site as it was washed by the incoming tide. No other biological weapons trial was done at Penclawdd and no other species of bacteria were used."
