Venezuelan opposition leader Juan Guaido promised "a great mobilization in Caracas" when he returns to the country after a two-week international tour, drumming up support to dislodge President Nicolas Maduro.
Recognized as interim president by more than 50 nations, Guaido said in Miami on Saturday he would end the "tragedy" in his country, which has been battered by political and economic crises.
"In the next few days, despite the risk, we will be entering Venezuela," Guaido said at a convention center near the airport.
Guaido defied a travel ban imposed by local authorities to leave the country and meet with officials abroad.
"There is only one option -- to achieve free elections," he added, calling on Venezuelans to be "prepared for the announcement of a great mobilization in Caracas."
