Thousands of farmers have taken to the streets of Bogota, the Colombian capital, to vent their anger at Juan Manuel Santos, the Colombian president.

They say his government has failed to meet its promises of help after Santos made a deal with striking farmers earlier this year.

Farmers say they are sliding further into poverty as they sell crops below production costs.
