Tear gas fired on protesters in Caracas

CARACAS, Venezuela — Security forces fired tear gas at supporters of Venezuelan opposition leader Juan Guaido as they marched in eastern Caracas on Tuesday morning, hoping to inject new life into a campaign to oust President Nicolas Maduro.

Women and men wearing white T-shirts and Venezuelan flags draped over their shoulders chanted and held signs that said “no more torture, no more deaths.” Police in anti-riot gear stood on the sidelines of the opposition’s gathering.

Mr. Guaido enjoys the backing of Washington and its allies, who recognize him as the nation’s legitimate leader, but he has so far failed to make much headway back home.

Last April, Mr. Guaido tried to lead an uprising, which collapsed after most of the armed forces declined to join. Despite this, the government has refrained from arresting him, possibly fearing the international reaction.

Hundreds of opposition supporters also rallied in other major Venezuelan cities such as Maracaibo, San Cristobal and Barquisimeto.
