"I can confirm that the German representation of the FRG in the OPCW received yesterday a Russian note on the situation with the poisoning of Alexei Navalny," RIA Novosti quoted her as saying.
As noted by Fitz, diplomats will respond to it within ten days.
On September 23, Moscow sent a note to the German mission to clarify the situation with Navalny.
In particular, the Russian side asks to transfer the test results, biomaterials and other clinical samples that Berlin has.
