The president of Poland apologized to Russia on Wednesday for the attack by a nationalist mob on the Russian Embassy in Warsaw, calling the episode outrageous and unjustifiable, Ria Novosti reported. "We need to apologize on behalf of the Polish state," President Bronislaw Komorowski said. Thousands of people paraded through Warsaw on Monday to mark the 1918 reunification of Poland after more than a century of being partitioned by Russia, Prussia and Austria. A crowd of youths attacked the Russian Embassy, pelting it with rocks and firecrackers and setting alight the guards’ booth. Moscow called for an immediate apology from Poland and demanded that Warsaw pay for the damages and ensure that those responsible were brought to justice.
