The clashes occurred as Venezuelan opposition leader Mr Guaido – who has been recognised as Venezuela's interim leader by Colombia, the US and UK among other countries – gave a personal send off to an aid caravan from the Colombian city of Cucuta. Mr Guaido briefly boarded one of a dozen trucks carrying US-backed humanitarian aid before they set off towards the border, where they were pushed back by Venezuelan security forces. Colombia's government said their contents would be unloaded and transported by "human chains" that have formed on the road that leads toward Venezuela.
