Anti-riot police clashed with farmers, indigenous people in Cauca, all unhappy with the government.
It’s the latest in a string of confrontations by farmers, who say the president’s agriculture and economic policies leave them unable to make profits.
Despite the president naming five new ministers, in a new ‘cabinet of unity and peace’, protesters blocked the Pan American highway. Police used tear gas to try to disperse the crowds.
Local media claim around 10,000 people were involved in blocking the main artery in at least three southern regions of the country.
Meanwhile, demonstrators used some 50 trailers to block one of the main roads leading to the capital Bogata where tyres were burst and petrol was split.
Demonstrators say the road will remain blocked until the Government agrees to negotiate.
