Was Worthing Toxic Cloud Mustard Gas?

Possible, I suppose.
"A toxic cloud which left up to a dozen people vomiting on Worthing beach may have been poison gas leaking from a munitions ship dating back to the First World War.
An investigation is now underway by The Maritime and Coastguard Agency after a toxic haze saw people evacuated from the seaside resort in East Sussex following complaints of sore eyes and vomiting on August 11.
Following the incident, it is now feared that the cloud may have been caused by the dozens of cargo vessels and munitions ships containing weapons and poisonous gas that were sunk in the English Channel during the war from 1914-1918.
In May, deadly mustard gas leaked from a First World War underwater 'weapons cemetery' in the North Sea, close to the Belgian coast.
Traces of the gas - which killed thousands of soldiers in the conflict - have since been found in at least two locations in the North Sea close to the Flanders coast in Belgium.
