The clean-up operation following Monday night’s farmers’ protests in several parts of the Netherlands continued on Tuesday morning as council officials cleared rubble and other waste from several roads.

According to the Telegraaf, several people were injured in traffic accidents caused by the protests and two were taken to hospital.

The Oldenzaal slip roads for the A1 remained closed to rush hour traffic in both directions because of the rubbish which had been dumped and set on fire.

In some places, farmers left bales of hay and started fires, and on the A50 near Beekbergen in the east of the country farmers set fire to asbestos, the regional police reported. The road was closed for a time.

On the A7 near Purmerend, 25 tractors blocked the motorway and there were also protests on motorways near Breukelen, Nunspeet, Vuren, Veenendaal, and Steenwijk, broadcaster NOS said.

“Dumping and setting fire to rubbish is a danger to health and the environment, as well as leading to dangerous situations on the road,” Oost-Nederland police said in a statement.

Farmers have been protesting throughout Europe about the EU’s Green Deal and other plans, and last week the campaign spread to the Netherlands. Radical farmers group Farmers Defence Force has pledged a mass protest this week
