Moscow, Sep 10 (TIWN) The Russian Foreign Ministry said that it has summoned the German Ambassador to Moscow, Geza Andreas von Geyr and expressed a strong protest in connection with the "unfounded accusations and ultimatum" related to the alleged poisoning of opposition leader Alexei Navalny.

The ministry also accused Berlin of an "obvious use of the situation that has arisen with it as a pretext for discrediting our country in the international arena," it said in a statement. 
  
Moscow also demanded that Germany provide Navalny's medical examination results and test samples for the comprehensive study by and verification of Russian specialists, the statement said. 
  
Russia will regard the failure to provide the materials as a refusal of the German government to establish the truth and its actions in connection with Navalny as a "gross hostile provocation against Russia, fraught with consequences for Russian-German relations, as well as a serious complication of the international situation," it said.
