MOSCOW, May 9. /TASS/. Polish authorities have turned a blind eye to the provocation against Russian diplomats on May 9, so Moscow will make a firm protest to Warsaw over this situation, the Russian Foreign Ministry said in a statement on Tuesday,

The Foreign Ministry said that the crowd had not let the Russian diplomats walk through to the Soviet Military Cemetery in Warsaw to lay flowers and "thus disrupted the commemoration."

"The Polish Foreign Ministry was in advance notified of the ceremony planned by the embassy. The Polish authorities, however, did not prevent the provocative actions of the ‘protesters.’ The Polish side will be strongly protested," the ministry said.

"We consider this to be another manifestation of unfriendly attitude from the Polish side, and above all, to be an affront to the memory of more than 600,000 Soviet soldiers, who fell liberating Poland from the German occupation, and a failure to comply with obligations to prevent such incidents," the Russian Foreign Ministry stressed.

The Foreign Ministry added that this policy of the Polish authorities "will not remain without proper response" from Russia.

"The incident has once again shown the duplicity of Warsaw’s policy in evaluating the World War Two events and in attempting to drive into oblivion our nation’s role in saving European countries enslaved by Nazi Germany," the statement states.

On Tuesday, an aggressive crowd did not let Russian Ambassador to Poland Sergey Andreyev and other Russian diplomats walk through to the Soviet Military Cemetery in Warsaw to lay wreaths at the monument.

Founded in 1950, the Soviet memorial cemetery, located on Zwirki i Wigury Street in the Polish capital, is the burial place of about 22,000 Soviet soldiers, who died liberating Poland from the Nazis. The memorial plaque says in two languages, ‘Eternal glory to the Soviet soldiers who fell liberating Poland from Nazi invaders in 1944-1945.’ In total, more than 600,000 Soviet soldiers were killed in the Polish territory during World War Two.
