"On April 30, I'll arrive in Przemyśl along with many Ukrainian politicians. We already have information that there may be attempts to frustrate the planned anniversary. It is important for us to explain to the Polish society, Polish authorities and Polish people that what may happen in no way concerns any negative attitude towards Poland," he said during the round table meeting "Akcja Wisła - the crime of the Polish communist regime" on Thursday in Kyiv.
Speaking about the operation itself, Kniazhytskyi noted that the Ukrainian side blames the tragedy on the Polish communist regime and not on the current government.
On April 28, 1947, the Polish authorities launched Operation Wisła aimed to forcibly deport thousands of Ukrainians.
Operation Wisła (Akcja Wisła) was a codename for the 1947 forced resettlement of Ukrainian minority from the south-eastern provinces of post-war Poland to the recovered territories in the west of the country. In three months beginning April 28, 1947 with the Soviet approval and aid, about 141,000 civilians residing around Bieszczady and Low Beskids were forcibly resettled to formerly German territories, ceded to Poland at the Yalta Conference at the end of World War II. On Aug. 3, 1990, the Polish parliament condemned this cruel resettlement of Ukrainians.
