Ambassador of the Russian Federation to Poland Sergey Andreyev was summoned to the Polish Foreign Ministry on Tuesday after the head of the Polish Institute of International Affairs was denied entry to Russia, Artur Lompart, head of the ministry's press office, informed PAP.

Deputy Foreign Minister Andrzej Papierz presented the ambassador with a diplomatic note in which Poland demanded an explanation of the incident, Lompart added.

According to media reports, Russian Border Guard officers stopped the head of the Polish Institute of International Affairs Sławomir Dębski at Moscow Domodedovo airport denying him the right to enter Russia.

Lompart said that Dębski left Moscow for Frankfurt am Main early on Tuesday morning. Earlier, Dębski was offered assistance by Poland's consular service. The cause for refusal of entry is still unknown.

Later in the day, Dębski told PAP that Russian authorities had imposed a three-year entry ban on him while his five-year Russian visa was annulled.

Dębski explained he was travelling to Russia to take part in a conference on Russia's foreign policy - "Primakov Readings" - to which he had been officially invited by the organiser of this annual event - the Institute of World Economy and International Relations of the Russian Academy of Sciences.

The head of the Polish Institute of International Affairs added that he was denied entry to Russia without any justification. (PAP)
