Belarus–Poland border
The Belarusian-Polish border is the state border between the Republic of Poland (EU member) and the Republic of Belarus (Union State). It has a total length of , or (sources vary). It starts from the triple junction of the borders with Lithuania in the north and stretches to the triple junction borders with Ukraine to the south. It is also part of the EU border with Belarus. The border runs along the administrative borders of two Voivodships Podlaskie and Lubelskie in the Polish side and Grodno and Brest Vobłasć in the Belarusian side. In the Polish side , the section is under the protection of the Podlaskie Border Guard Unit, while the section is in the operation area of the Bug River Border Guard Unit. Border rivers (from north to south) are Czarna Hańcza, Wołkuszanka, Świsłocz, Narew, and Bug. History. After the Soviet invasion of Poland in September 1939, the area of West Belarus was annexed into the Byelorussian Soviet Socialist Republic. Five new Voblasts were created: Baranavichy, Belostok, Brest, Pinsk, and Vialejka. In accordance with the Border Agreement between Poland and the USSR of 16 August 1945, 17 districts of Belastok Voblast of the BSSR including the  city of Białystok and 3 districts of Brest Voblast, where a significant number of Poles lived, were transferred to Poland. Following the 1944 agreement on population exchange between Poland and Soviet Belarus, on November 25, 1945, an additional agreement was signed in Warsaw by representatives of the government of the Byelorussian Soviet Socialist Republic and the Government of the National Unity of the Republic of Poland on the registration and evacuation of the Belarusian population from the territory of Poland to the BSSR and Polish population from the BSSR to the territory of Poland. Announcements on registration and extension of  the evacuation until June 1946 were posted in Białystok and within the Voivodship. In 1946, during the refinement of the state border between the USSR and Poland in the Belarusian-Polish section, Krynek, which was entirely granted to Poland, had a point that separated the border section under Sub-Committee V from the activities of Sub-Committee VI. Further, the border ran through areas which Poland lost due to the Soviet dictate, because they were located on the west side of the Curzon Line. This shift was around 12 km in the vicinity of Odelsk, 15 km in the Łosośny  area, 20 km in Biała Blota, and 15 km in the area of the Augustów Canal. Polish negotiators during the delimitation procedure realized that they were helpless in the face of these imposed arrangements and were only trying to introduce minor verifications for Poland. Among other things, near Odelsk, within the borders of Poland was the village of the villages of Klimówka, Minkowce, Nomiki, Taki, Tołcze, Szymaki of the Hrodna District and the villages of Todorkowce and Chworosciany of the Sapotskin district were transferred to the Polish People's Republic. Zubrzyca Wielka and Zubrzyca Mała were also recovered, but most  of the agricultural lands belonging to these villages remained on Belarusian side of the border. More to the north, in the area of the village of Nowrowol the border was moved 700-800m to the east, which also allowed the villages of Tołcze, Szymaki and Klimówka to be part of Poland. In the Gmina Kuźnica, the border line was moved 200-300m to the east and at this place the border was cut across the tracks of the Białystok-Grodno railway line. In August 1948, the TASS agency announced a communication on the completion of delimitation of the  border. However, the local authorities determined the final shape of the border and belonging of individual villages or their fragments for more than a year and a half. On the basis of documentation of the Belarusian side, officially announced on July 8, 1950, the Polish side obtained 30 villages as part of exchange and border corrections, while the Belarusian side obtained 12 villages. Also, many villages have been divided. Thereafter, and until now, the border between Poland and Belarus has never changed. 2021 dispute. In August 2021, a wave of illegal immigrants started fleeing through Belarus to Poland. Belarus was  accused of hybrid warfare by orchestrating and supporting illegal crossing of the border in forest areas. Poland has recently reinforced the border with 1,000 men and is planning to build a border fence due to a massive influx of immigrants. The Poland–Belarus barrier is expected to be completed in June 2022. Over 2000 immigrants tried to illegally cross the Belarus border and 800 were successful, landing in state-run centres issued to aid them, many of which have been waiting near the border for more than a week. Poland's prime minister Mateusz Morawiecki stated that Poland must protect  its borders and the people crossing the Polish—Belarussian border are being used by Lukashenko. On 25 August 2021, the European Court of Human Rights (ECHR) summoned Poland and Latvia to provide the migrants "food, water, clothing, adequate medical care and, if possible, temporary shelter", according to a statement from the court. "The measure will apply for a period of three weeks from today until 15 September 2021 inclusive", with the ECHR judge citing the European Convention on Human Rights, while stating that neither country was ordered to allow the migrants through the border. On 24 November 2021, the "Human  Rights Watch" reported that thousand of people were stuck at the border of Belarus and Poland in circumstances that violated human rights and put their lives at risk. Polish officials pushed back those who try to cross while Belarusian officials beat and detained those who return. People have spent days or weeks in the open on the border, without shelter or access to basic humanitarian services, including food and water, resulting in deaths. On 15 February 2022, OHCHR reported that human rights defenders, including media workers and interpreters face threats and intimidation at the border with Belarus. The organization called  on Poland authorities to investigate all allegations of harassment and grant access to journalists and humanitarian workers to the border area ensuring that they can work freely and safely.
