Milky Way: Infuriated farmers spray milk on riot police in Brussels. (VIDEO)

Thousands of dairy farmers on Monday protested low prices for their product, choking traffic in the Belgian capital with their tractors and spraying European Union headquarters and police with milk.

One group started a fire in the street, but despite some pushing and shoving with police, there was no major violence.

Farmers from several EU nations are demanding higher prices for milk, which currently is often being sold at below production costs, threatening the survival of their farms.
