The global
chemical weapons watchdog, which has been asked by
Germany to test samples of what
Berlin says was a banned nerve agent used to poison a
Russian opposition figure, said on Monday its experts would be prepared to assist
Russia in the case.

The Organisation for the Prohibition of Chemical Weapons (OPCW) said it had received a request from
Moscow on Oct. 1 for help in the case of
Kremlin critic Alexei Navalny, and was seeking clarification on what type of assistance Russia wanted.
Navalny fell ill on a flight in Siberia on Aug. 20 and was flown to Germany for treatment.
