US Air Force C-17 cargo aircraft left the Homestead Air Reserve Base in Miami and landed in Cucuta, Colombia, according to a statement by the US Agency for International Development (USAID) . The relief supplies provided included sanitary kits that can help about 25,000 people and nutritional products that according to USAID can feed about 3,500 children.

The self-appointed provisional president of Venezuela, Juan Guaido, urged the hundreds of thousands of volunteers registered on Saturday to help aid in the country.
Speaking to a demonstration of volunteers in Caracas, Guaido said that "the end of poverty will come, the humanitarian emergency will cease", urging that aid be allowed to enter and "humanitarian corridors open".
tweet Saturday at least 600,000 had registered as volunteers.
CNN was not able to independently verify the number.
Guaido also repeated his call directly to the armed forces to support his efforts to get help.
Maduro refused international aid, saying: " We are not beggars ".
Guaido declared himself interim president on January 23, but Maduro – who was inaugurated for a second term that the United States, dozens of other countries and Venezuelan opposition denounced as illegitimate – did not resign as president or considered calls to hold another election.
A senior administration official says the United States would be willing to meet Maduro to negotiate his exit.
According to reports, Maduro extended an invitation to meet with the US special envoy on Venezuela, Elliott Abrams. The State Department and the secretary of state have not commented on the prospect of such a meeting, but Mike Pompeo said on Friday that the overture shows "the growing understanding of Maduro that the Venezuelan people are rejecting it".
Speaking at the Munich Security Conference on Saturday in Germany, US Vice President Mike Pence said the situation in Venezuela is a "tragedy that requires a response from around the world".
Pence added that the United States was "proud" to be the first country to recognize Guaido and "to date, 52 countries, including 30 of our European allies, have followed the command of America."  Pence said it is time for the rest of the world to recognize Guaido.
"It's time for the rest of the world to take a step forward," he said. "Once again the Old World can take a stand in support of freedom in the New World. We all have to be with the Venezuelan people until freedom and democracy are fully restored."
