On Friday, OAS head said that to resolve the situation in Venezuela one can not rule out any options, including a possible military invasion.
"As for the garbage, which is OAS secretary general,… he is in the scrapyard of history. Venezuela is a country of men and women who will force such garbage as this one to respect them," Maduro said at a press conference in Caracas.
"If you say that you need to invade Venezuela, prepare your rifle. We are waiting for you here," Maduro said.
Earlier on Tuesday, the National Constituent Assembly of Venezuela issued a statement demanding immediate resignation of Almagro.
The Constituent Assembly also created a special commission, which would have to compile a list of acts of the "systematic aggression" against the country through violence, economic and financial blockade.
