Thousands of Venezuelans marched and participated in a mass rally in Caracas to oppose the activity of Colombian paramilitary groups on the border and to show their friendship with the Colombian people. The mobilization took place after both Venezuela and Colombia recalled their ambassadors on Thursday night. Ten days ago Venezuela had closed part of its border in an operation aimed at putting a stop to the mass smuggling of subsidized food, fuel and medical supplies out of the country and into Colombia. teleSUR.
