 Thousands of Polish farmers Friday staged blockades at 250 locations and blocked border crossings into Ukraine to protest European Union climate change measures and the flow of agricultural goods into the country. Polish media and video on social media showed long lines of tractors at several border crossings with Ukraine and on highways around cities throughout the country. Police in Warsaw issued traffic warnings for much of the nation, particularly at the Ukraine border. In Poznan, about 300 kilometers west of Warsaw, farmers parked about 1,000 tractors in front of the regional government offices. Poland's Farmers Union said these actions kick off a month-long general strike. While Poland joins farmers from those nations in protesting the EU-imposed environmental regulations, Poland's Farmers Union and agricultural leaders say they have been heard in particular by the flow of cheaper goods coming into the country from Ukraine, creating unfair competition. In an interview with Pulsat, Poland's Agriculture Minister Czesław Sikirski said the striking farmers have legitimate complaints and are protesting in the interest of all of us as consumers.
