State Department warns US citizens to leave Venezuela

Venezuela's acting president, Delcy Rodriguez, and Cuban President Miguel Díaz-Canel have both announced days of mourning following the U.S. operation in Venezuela.

Cuba will have two days of mourning for the 32 members of the military who were killed.

Granma, the official newspaper of Cuba’s Communist Party, also posted images of the fallen military personnel with a headline, “Honor and Glory!”

Rodriguez announced that Venezuela would recognize a seven-day mourning period to honor "the young men and women who died, offering their lives, defending Venezuela, defending President Nicolas Maduro."

"There's no peace here because we're not at war," Rodriguez said. "We're a people and a country of peace that was assaulted and attacked."

Venezuela is turning over 30 million to 50 million barrels of oil to the United States, according to President Donald Trump.

"This Oil will be sold at its Market Price, and that money will be controlled by me, as President of the United States of America, to ensure it is used to benefit the people of Venezuela and the United States!" he said Tuesday in a statement on social media.

The oil will be "taken by storage ships, and brought directly to unloading docks in the United States," Trump said.

He said he has asked Energy Secretary Chris Wright to "execute this plan, immediately."

Venezuela has roughly 303 billion barrels of crude oil, or about 17% of the world's reserves, according to the U.S. Energy Information Administration, a government agency.

The U.S. uses roughly 20 million barrels of oil per day and produces approximately 13.4 million barrels of crude oil a day, according to the agency and trade groups.

Venezuela has demonstrated its "true character" in its response to the U.S. attack, the country's interim president, Delcy Rodriguez, said during a press conference on Tuesday.

Rodriguez said Venezuela is showing that it's a country that "refuses to surrender," is "in active resistance" and is made up of a "dignified people."

"It's Venezuela that has demonstrated to the world our true character, that we've become stronger, that we've grown spiritually to confront the challenges, the attacks, the threats," Rodriguez said in Caracas on Tuesday, one day after being sworn in as the country's de facto leader.

The Saturday operation led to the capture and ouster of Venezuelan President Nicolas Maduro and his wife, Cilia Flores, and the death of at least 50 Venezuelan and Cuban security officials, according to the countries.

Venezuelan Interior Minister Diosdado Cabello claimed there is a rising anti-American sentiment in the country after the U.S. military operation while speaking during a pro-Maduro rally in Caracas on Tuesday.

"What has risen in this country is a terrible anti-American movement for them, who murdered innocent civilians, people who had nothing to do with politics. However, the Bolivarian Revolution will go ahead," Cabello said.
