Russia is asked to inform the UN Security Council.
The Permanent Representatives of France, Germany, Great Britain, Belgium, and Estonia to the UN have called in a letter on Russia to urgently disclose the circumstances of the poisoning of Russian opposition leader Alexei Navalny with a poisonous substance from the Novichok group.
The letter whose copy is available to Russia's news agency Interfax is addressed to Permanent Representative of Niger to the United Nations and President of the Security Council for the month of September Abdou Abarry and UN Secretary-General António Guterres.

"As such, we consider that the use of a chemical nerve agent from the Novichok group in the abhorrent poisoning of Mr Alexei Navalny constitutes a threat to international peace and security," they said in the letter.
"We call on the Russian Federation to disclose, urgently, fully and in a transparent manner, the circumstances of this attack and to inform the Security Council in this regard."
Speaking at a press conference on Thursday, October 1, which was dedicated to the beginning of Russia's presidency of the Security Council, Permanent Representative of the Russian Federation to the United Nations Vassily Nebenzia advised Germany and other countries "cooperate with the Russian authorities" instead of "drafting letters in a hurry before the end of Niger's presidency of the Security Council."
