Poland sees its most violent farmers' protest yet Anger grows across Europe

Police used tear gas and said they detained over a dozen people and prevented the protesters from getting through to the Sejm, the Polish parliament.

Farmers are angry at EU climate policies and food imports from Ukraine. Many similar protests have occurred across the 27-member EU in recent weeks, but this one was decidedly angrier than earlier demonstrations in the central European nation.

Police noted on the social media platform X that its officers "are not a party to the ongoing dispute" and warned that behaviour threatening their safety "cannot be taken lightly and requires a firm and decisive response".

The deputy agriculture minister, Michał Kołodziejczak, said he didn't believe that "real, normal farmers caused a riot in front of the Sejm today", and that it was necessary to isolate "provocateurs and troublemakers".

He did not say who he thought was behind the violence.

Farmers on tractors blocked highways leading into Warsaw while thousands of their supporters gathered in front of the prime minister's office before marching to the parliament. Some trampled an EU flag and burned a mock coffin bearing the word "farmer".

Among the crowd were miners, foresters, hunters and other supporters. They blew horns and set off firecrackers and smoke bombs, despite police warnings that the use of pyrotechnics was banned. Some protesters burned tires.

No backing down

The protesters are demanding a withdrawal from the EU's Green Deal, a plan meant to fight climate change and protect biodiversity with plans including requiring farmers to reduce the excessive use of polluting chemicals to boost their crops.

The protests have led politicians to water down some provisions.

The protesters also want the Polish-Ukrainian border closed to stop the imports of Ukrainian food products, which farmers say drive down market prices and put Poland's agricultural sector in jeopardy.

The protest increased pressure on the still-new government of Prime Minister Donald Tusk, a former president of the European Council, who is strongly pro-EU and seeks to support Ukraine as it fights Russia's invasion.

Tusk has sought to meet the farmers' demands, calling their frustrations justified. He has said he plans to propose amendments to the Green Deal.

Anti-Ukrainian slogans have featured at the protests in Poland, where authorities have said they are concerned that Russia is trying to leverage legitimate concerns to create divisions between Warsaw and Kyiv.

Agriculture, forestry and fishing make up less than 3% of Poland's GDP, according to the World Bank.
