The Russian ambassador to Warsaw, Sergei Andreyev, has not been summoned by the Polish Foreign Ministry, a Russian Foreign Ministry official said Tuesday.
A Polish government source said earlier on Tuesday that Andreyev had been summoned over a spat regarding the 70th anniversary of the end of the World War II.
"Our embassy in Warsaw denies that," a Russian foreign ministry official said.
Russia's Itar-Tass news agency also reported from Warsaw that the Russian ambassador had not been summoned.
