Activists had scuffled with police and troops ahead of the rally, meant to pressure Maduro amid the blackout, which the governing Socialist Party called an act of U.S.-sponsored sabotage but opposition critics derided as the result of two decades of mismanagement and corruption.

Dozens of demonstrators attempted to walk along an avenue in Caracas but were moved onto the sidewalk by police in riot gear, leading them to shout at the officers and push on their riot shields. One woman was sprayed with pepper spray, according to a local broadcaster.

The power flickered on and off in parts of Caracas on Saturday morning, including the presidential palace of Miraflores, according to Reuters witnesses. Six of the country’s 23 states still lacked power as of Saturday afternoon, Socialist Party Vice President Diosdado Cabello said on state television.

“We’re all upset that we’ve got no power, no phone service, no water and they want to block us,” said Rossmary Nascimiento, 45, a nutritionist at the Caracas rally. “I want a normal country.”
