Polish President Bronislaw Komorowski has apologized to Russia for anti-Russian rioting in Warsaw.
In an interview with Polish Radio ZET on November 13, Komarowski said the events "cannot be justified by anything, it is only possible to apologize for this."
On November 11, far-right Polish demonstrators threw firecrackers toward the Russian Embassy, set a guard's station on fire, and tried to climb the embassy fence during an Independence Day march.
Security forces controlled the protesters.
Police said on November 12 that 72 people were arrested over the rioting and for attempts to break into the Russian Embassy.
Russia's Foreign Ministry had demanded an official apology from Poland.
Meanwhile, reports say four people were detained in Moscow on November 13 after throwing firecrackers at the Polish Embassy.
