At least 1,300 farmers from across Europe lined the streets of Brussels with their tractors at the annual summit of European Union (EU) leaders on Feb. 1 to protest policies they claim threaten to put them out of business, according to Bloomberg and other news sources.

The latest demonstration against restrictive “net zero” and other government policies gained traction over the past week as owners of small and family-owned farms from France, Spain, Italy, Portugal, Germany, Poland, the Netherlands, Great Britain and other EU countries made their way to Belgium to surround the EU Parliament headquarters building.

The mostly peaceful protest was punctuated by police deploying water cannons and shooting rubber bullets, and by farmers breaking through barricades to throw eggs and set off fireworks, small fires and smoke bombs, according to Zerohedge. The farmers also toppled a statue, France24 reported.
