CARACAS, Venezuela — Jailed Venezuela opposition leader Leopoldo López is urging supporters to keep demonstrating as an anti-government protest movement that has claimed more than 60 lives enters its third month.

A young man who was set ablaze during a May protest in a wealthy part of Caracas succumbed to his injuries on Sunday.

Protesters took to Caracas’ streets again Monday, shutting down main roads to demand new presidential elections after the release of a video in which López expressed support for the movement. The video was recorded at the military prison where López has been held since leading a wave of street protests in 2014.

Former Spanish President José Luis Rodríguez Zapatero and Foreign Minister Delcy Rodríguez visited López at the prison on Sunday. The politicians did not say what they discussed.
