Brazil says it will send humanitarian aid to its border with Venezuela by the weekend, despite the protests of embattled President Nicolás Maduro.The delivery and distribution of the aid is being organised by Venezuelan opposition leader Juan Guaidó, the Brazilian presidential spokesman said.
Mr Maduro denies there is a crisis in Venezuela and calls the growing aid operation a US-orchestrated show.
Venezuela also closed its border with the Dutch island of Curacao.
The Caribbean island, off Venezuela's north coast, is planning to host US aid. Senior Venezuelan military commander Vladimir Quintero confirmed the closure of the air and sea border on Tuesday, but gave no further details.
The military has so far managed to block shipments of US aid from coming across the border with Colombia.
Meanwhile, Venezuela's military has reaffirmed its support for President Maduro, rejecting a call by US President Donald Trump to switch allegiance to Mr Guaidó.
