CUCUTA, Colombia (Reuters) - A convoy of trucks carrying humanitarian aid for Venezuela left warehouses in Colombia headed for the nearby border crossing on Saturday, despite Venezuelan President Nicolas Maduro’s insistence they would not be allowed to cross.

Speaking on the Colombian side of the border, Venezuelan opposition leader Juan Guaido, recognized by most western nations as Venezuela’s legitimate leader, called on troops to allow the convoy to cross. Alongside him, Colombian President Ivan Duque said Maduro would be responsible for any violence.
