Trucks full of food and medicine have arrived at the Venezuelan border, setting up a showdown between President Nicolás Maduro and U.S.-backed opposition leader Juan Guaidó.
The aid convoy arrived at the Colombian border city of Cúcuta, The Associated Press reports, but Maduro and the military have blocked the Tienditas bridge so that the trucks cannot enter Venezuela.
"The United States is prepositioning relief items — including food, nutritional supplements, hygiene kits and medical supplies — in Colombia so they are available to reach those most in need in Venezuela as soon as possible," a U.S. official told The AP.
Maduro has rejected aid offers and says his country has "never been, nor are we, a country of beggars," the BBC reports.
Venezuela has been in a political crisis since Guaidó, the president of the National Assembly, declared himself interim president last month. Maduro has refused to step aside and accuses the U.S. and others of attempting to overthrow him. Venezuela's economy and medical system have collapsed in recent years, sending millions fleeing from the once-rich country, home to the world's largest oil reserves.
Meanwhile, Colombia's migration office has canceled more than 300 daily entrance passes used by Venezuelan politicians and the families of Maduro supporters.
"It doesn't make sense that while [the Venezuelan people] migrate for hunger and need, supporters of the dictatorship enjoy these benefits and enter our country, using this card, to shop, among other things," Christian Krüger Sarmiento, the director general of the migration agency, said in a statement.
U.S. Secretary of State Mike Pompeo tweeted a photo of the barricaded bridge. "The Venezuelan people desperately need humanitarian aid. The U.S. & other countries are trying to help, but Venezuela's military under Maduro's orders is blocking aid with trucks and shipping tankers. The Maduro regime must LET THE AID REACH THE STARVING PEOPLE."
Guaidó has been talking about the aid convoys. "While we work every day to successfully achieve the delivery of the humanitarian aid; they insist on taking away the medicines and foods of those who need them urgently," he tweeted.
"The first phase continues with collection centers in three allied countries," he wrote, posting photos of the trucks.
Maduro has called the convoys "a political show," according to Reuters.
