Some 10,000 to 15,000 people from trade unions, environmental and consumer groups have taken part in protests against the US-EU Transatlantic Trade and Investment Partnership (TTIP) and Canada-EU Comprehensive Economic and Trade Agreement (CETA) on Tuesday, the organizers said, according to AP. Police put the number of protesters at 6,000.

Thousands of people demonstrate against the Transatlantic Trade and Investment Partnership (TTIP) and the EU-Canada Comprehensive Economic and Trade Agreement (CETA) in the centre of Brussels, Belgium September 20, 2016.
"We are against these trade deals because they are a threat for the environment, for health, for labor regulations and they give so much power to multinational corporations," said Mark Brady, spokesman for Greenpeace Europe.

The protest is held in hope that the talks between the US and the EU scheduled for Friday in Bratislava will falter due to lack of support from Europe.
Protesters also hope that the CETA deal won't have enough parliamentary approvals among the EU states, and the deal that is already finalized, but still needs approval, will come off the table.
Three days ago seven German cities, including Berlin, Cologne, Hamburg, Frankfurt, Leipzig, Munich, and Stuttgart saw similar demonstrations. At least 100,000 protesters rallied in Germany, speaking out against the deals, Deutsche Welle reported, citing the German police.
