The leader of Venezuela's opposition-controlled National Assembly, Juan Guaido, canceled a rally scheduled to be held in the country's fourth-largest city on Sunday and said the "dictatorship" had prevented him from entering.
Guaido has traveled outside the capital, Caracas, more and more in recent weeks to pressure President Nicolas Maduro to step down. In January, he invoked the constitution to assume an interim presidency, arguing Maduro's 2018 re-election was illegitimate.
While he has previously reported delays in arriving to cities in the country's interior due to roadblocks by the armed forces and Maduro supporters, Sunday's cancellation of the event in the western city of Barquisimeto was unprecedented.
