“OPCW cannot estimate or determine the exact amount of the nerve agent used in Salisbury on March 4, 2018,” the OPCW representative stated.
Besides, the organization informed that the amount of the nerve agent used can be measured in milligrams, but not in grams, as Ahmet Üzümcü, the OPCW Director-General, said.
“Additionally, the analysis of the samples gathered by the group of OPCW experts, showed that the discovered chemical substance has a high degree of purity, and it is a persistent substance, having a resistance to the weather conditions,” the OPCW representatives commented on the results of the analysis.
Earlier, Ahmet Üzümcü, the OPCW Director-General, in the interview for The New York Times stated that 50-100 grams of a nerve agent in a liquid state could be used to poison the Skripals.
Ex-colonel of Russia’s Main Intelligence Agency, Sergey Skripal and his daughter were poisoned in the center of Salisbury town in the evening of March 4. The British special services suppose that Skripals were poisoned by his ex-colleague Andrey Lugovoy, who acted on orders from Moscow.
Theresa May, British Prime Minister, stated that Russia was highly likely to be involved in Skripal’s case. Later, Britain had officially confirmed the use of Novichok nerve agent in Salisbury. Due to this, British representative accused Russia of violating of UN Charter and Chemical Weapons Convention at the UN Security Council session.
As we reported on April 14, Sergey Lavrov, Russia's Foreign Minister claimed a chemical substance BZ, which was in service in the United States and Britain was used to poison Yulia and Sergey Skripals. Later Switzerland belied the statement of Lavrov.
The British intelligence assumed that Novichok, the nerve agent used in the attack on the Skripals, was produced at a Russian military research base in Shikhany town, Saratov Oblast. The MI reported that over the last decade, the Russian military has been testing the gas to find out whether it is suitable for covert murders abroad. However, Russia belied all accusations.
