Venezuelan interim President Juan Guaido is calling out the Venezuelan military, imploring them to allow aid into the country.
Medicine and food sent by the United States has been blocked on the border in Cucuta, Colombia after Venezuelan soldiers closed a bridge linking the two countries. Maduro still retains the crucial backing of the country's military top brass, who control the repressive apparatus created to protect the regime's authority and crush political dissidents by force.
"There are people responsible for this and the regime knows it".
The U.S. provided the aid and the Colombian government helped ensure its transport to the border, but the opposition is charged with handling the aid's distribution within Venezuela.
"(Guaido) will announce the day when, from Colombia, from the islands by sea, and from Brazil the humanitarian aid will arrive simultaneously", Toledo said.
"You must be ready to go to the heart of the enemy who dares touch Venezuelan soil - to go to the heart of the enemy and to tear out his heart in his own territory", he declared at a military event in Caracas.
This includes the Montevideo Mechanism - an global contact group formed in the Uruguayan capital on February 7 by 13 "neutral" countries in Europe and Latin America for the objective of resolving the Venezuelan crisis.
Speaking to AFP Friday, Guaido vowed to do "whatever necessary" to "stop the usurpation" of power and "save lives" - without ruling out the possibility of authorizing foreign intervention.
An global Contact Group, made up of European and Latin American countries, called for snap presidential elections following a meeting in Montevideo this week.
Guaido says Maduro's re-election was fraudulent and as head of the opposition-led National Assembly, he has the constitutional right to invalidate the results and declare himself president until a new election is held.
