President Donald Trump ramped up pressure on Venezuela on Tuesday by announcing that he is ordering a blockade of all “sanctioned oil tankers” entering and leaving the South American country.

Axar.az informs, citing NBC news, “Venezuela is completely surrounded by the largest Armada ever assembled in the History of South America," Trump wrote on Truth Social. "It will only get bigger, and the shock to them will be like nothing they have ever seen before."

He then added that he is "ordering A TOTAL AND COMPLETE BLOCKADE OF ALL SANCTIONED OIL TANKERS going into, and out of, Venezuela," arguing that Venezuelan President Nicolas Maduro's government is using oil revenue to finance illicit operations, including "drug terrorism."

The U.S. has sanctioned three of Maduro’s nephews and repeatedly conducted military strikes against boats from the Caribbean that it alleges are carrying drugs.
