"The struggle in Venezuela is between dictatorship and democracy," U.S. Vice President Pence said in Colombia. He was there to support Juan Guaidó, who has declared himself Venezuela's interim leader.

The meeting is set for Monday in Bogota, Colombia. At least four people were killed in clashes at the border Saturday, as military forces blocked humanitarian aid from entering the country.

President Nicolás Maduro issued the order in an apparent effort to make it harder for international aid to enter the country and buoy his political opponent, Juan Guaidó.

The military, which backs President Nicolás Maduro, has barricaded a bridge from Colombia. Opposition leader Juan Guaidó, along with the U.S., is demanding that the aid convoy be allowed to pass.

Francisco Yanez is the first high-ranking officer to publicly voice support of Venezuela's opposition leader, Juan Guaidó. Both anti- and pro-government demonstrations are taking place on Saturday.

Juan Guaidó accuses Venezuela's President Nicolás Maduro of sending police to intimidate his family. The U.S.-backed opposition leader seeks to oust Maduro and replace him as interim president.

Opposition leader Juan Guaidó called for nationwide rallies a week after he declared himself interim president and demanded Nicolás Maduro step down or call new elections.
