British police say there is "nothing to suggest that Novichok" caused two people to fall ill this weekend at a restaurant in Salisbury, where earlier this year the nerve agent was used in an attempted assassination.
Safety measures will be in place to protect mourners at the funeral of Dawn Sturgess, who was exposed the nerve agent Novichok in southern England earlier this month.
A small bottle discovered in the home of Novichok victim Charlie Rowley has been identified as the source of the nerve agent that killed his partner, London's Metropolitan Police said.
Authorities in the UK have opened a murder investigation after a British woman died from exposure to a Soviet-era nerve agent that had previously sickened a former Russian spy and his daughter.
