Surrounded by top military commanders, among them, Defense Minister Vladimir Padrino Lopez Mr Maduro announced that the border with Brazil would be closed “completely and absolutely” from 20:00 (23:00 GMT) on Thursday, until further notice.
The president also added: “I don’t want to take any decision of this type but I am evaluating it, a total closure of the border with Colombia.”

President Jair Bolsonaro
The right-wing Brazilian government of President Jair Bolsonaro is among those that recognize Mr. Guaidó as Venezuela’s legitimate leader, pending elections.
Presidential spokesman Gen Otávio Régo Barros said on Tuesday that, in co-ordination with the US, food and medicine would be available in the border town of Pacaraima to be collected by “the government of acting President Juan Guaidó in Venezuelan trucks driven by Venezuelans”.
“Brazil is taking part in this important international initiative to support the Guaidó government and the Venezuelan people,” he said.
