Sky News reported on Tuesday night that Waterloo International was the target of a foiled plot to launch a chemical attack in the UK.
Intelligence sources confirmed to Sky News that a plan to launch a chemical attack in the UK had been foiled.
They said a highly toxic chemical called osmium tetroxide was to be used in a device. The chemical compound, which can be bought on the internet, causes victims to choke to death in agony. It also attacks the cornea of the eye and can lead to blindness.
The security services are believed to have been alerted after a mention of the chemical was picked up at GCHQ.
Despite the current high state of alert, the Queen used the Eurostar terminal at Waterloo on Monday morning for her journey to Paris for a State Visit.
