“We’re going to do everything that has a lower social cost, that generates governability and stability to deal with the emergency,” said Guaido, 35.

He is trying to bring in food and medicines from the US but the supplies are stuck in warehouses in Colombia because the Venezuelan military has blocked their entry.

Earlier, Maduro vowed not to let in “fake humanitarian aid” and claimed Venezuela’s crisis has been “fabricated by Washington” to justify intervention.

Guaido says 300,000 people could die if desperately-needed aid isn’t brought in.
