Europe correspondent Nick Beake on the scene as farmers take to the streets in protest.
Footage from the Belgian capital shows smoke bellowing across the city, after farmers set fire to tyres, resulting in police firing water cannons to put out the flames.
Protesting farmers, who drove their tractors into the heart of the city and filled streets with manure, are angry at low food prices, cheap imports and new EU environmental measures.
Barbed wire was also placed outside EU institutions where agriculture ministers were due to gather.
The government could use legislation to force fairer prices on "corporations", or tax those corporations and give that money to farmers.
Not saying they should or not, or farmers are right or not, but it's not like the government is powerless here. At the end of the day, while under capitalism, the government is supposed to be our way of fighting back against large financial interests.
Ah but who do you think pays for the protests and meetings and such? In the Netherlands they had build a stage at a demonstration which was literally sponsored by a big agro company. Its all just a way to get their foot more into politics.
