Venezuelan opposition leader Juan Guaido on Saturday called on citizens nationwide to travel to the capital, Caracas, for a protest against socialist President Nicolas Maduro as the country's worst blackout in decades dragged on for a third day.

Addressing supporters in southwestern Caracas, Guaido — the leader of the opposition-run Congress who invoked the constitution to assume an interim presidency in January — said Maduro's government "has no way to solve the electricity crisis that they themselves created."

"All of Venezuela, to Caracas!" Guaido yelled while standing atop a bridge, without saying when the planned protest would be held. "The days ahead will be difficult, thanks to the regime."
