Earlier, investigators from the Organisation for the Prohibition of Chemical Weapons have arrived at the scene in the UK city of Salisbury where former Russian intelligence agent Sergei Skripal was poisoned earlier this month.
Recently, A total of 16 EU countries, as well as the US, Canada, Albania, Norway, Ukraine, Macedonia and Australia announced on Monday their decisions to expel around 100 Russian diplomats in connection with Moscow's alleged connection in the nerve agent attack on Skripal and his daughter in Salisbury.
On March 14, the UK envoy to the UN Security Council stated that the United Kingdom had asked the OPCW to independently verify its findings in the nerve agent attack against Skripal.
Reacting to the incident, the UK Prime Minister Theresa May has stated that it was "highly likely" that Russia was responsible for it. She later announced a package of anti-Russia measures, including the expulsion of Russian diplomats from the country, and the suspension of bilateral contacts between the countries.
Moscow also expelled UK diplomats in response to the UK move. Russia has strongly rejected the accusations and offered assistance in the investigation.
