"We consider that the use of a chemical nerve agent from the Novichok group in the abhorrent poisoning of Mr. Alexey Navalny constitutes a threat to international peace and security," Belgium, Estonia, France, Germany and the United Kingdom said in the letter sent on September 30 and seen by Sputnik.
The five countries called on Russia in the letter "to disclose urgently, fully and in a transparent manner the circumstances of this attack and to inform the Security Council in this regard."
Navalny fell very ill during a domestic flight in Russia and was treated in Omsk after the airplane made an emergency landing. After two days of treatment, the Russian doctors approved Navalny as being fit for air transport to a hospital in Berlin, Germany.
The German authorities soon claimed traces of a nerve agent from the Novichok family were found in Navalny’s organism, but did not provide proof to back up their claim. The doctors in Russia have insisted they found no signs of toxins prior to Navalny’s departure.
Russia has denied any involvement and has repeatedly asked for evidence, which has so far not been provided. The Kremlin has rejected Navalny’s own accusations being poisoned as groundless, insulting and unacceptable.
