Venezuelan opposition leader appears at Colombia concert

CUCUTA, Colombia -- Defying orders banning him from leaving the country, Venezuelan opposition leader Juan Guaido made a surprise appearance at a star-studded aid concert in neighboring Colombia, joining thousands of other Venezuelans in pressuring President Nicolas Maduro into allowing the delivery of emergency food and medicine.

On the Venezuelan side, a much smaller crowd gathered for a rival, three-day "Hands Off Venezuela" festival being organized by Maduro. Even as several million Venezuelans flee the country and those who remain struggle to find basic goods such as food and antibiotics, the embattled president claims the relief effort led by Guaido is a U.S. orchestrated ploy to oust him from power.

The optimistic mood at the Live Aid-style concert opened in the Colombian border city of Cucuta couldn't mask underlying tensions a day before Maduro's opponents embark on a risky strategy to undermine Maduro and bring in the aid being amassed along three of Venezuela's borders. But the crowd reacted with joy when Guaido suddenly appeared.

He was greeted with shouts of: "Juan arrived! Juan arrived!"

Thousands of miles away, near a crossing with Brazil, a member of an indigenous tribe was killed and 22 more injured in clashes with security forces who enforced Maduro's orders to keep out the aid.

Hours before the concert in Cucuta began, dozens of Venezuelans hiked across the border through high bushes on an unmarked trail. They carried ice boxes, snacks and water and whispered directions as they kept a close eye out for Venezuelan soldiers.

"This concert happens once in a lifetime," 19-year-old Shirley Duran said. "It will be a great opportunity for so many poor people who are suffering under the heat, who are hungry, jobless. At last they'll have something to enjoy."

British billionaire Richard Branson organized the "Live Aid Venezuela" concert, which features dozens of Latin musicians performing on a giant stage on one side of what Colombian authorities have renamed the "Unity" bridge. Not far off sits a giant shipping container and tanker Maduro's government has placed on the bridge to prevent the delivery of U.S.-supplied food and medical kits.

As Venezuela's political turmoil drags on, allies of Guaido, who the U.S. and dozens of other countries have recognized as Venezuela's rightful leader, are hoping the massive concert in Cucuta will set the stage for the smooth delivery Saturday of the aid and a turning point in their quest for a transitional government. The promised "humanitarian avalanche" is taking place exactly a month after Guaido declared himself interim president in an outdoor rally.

At the concert venue, the feeling was one of collective catharsis, especially for migrants who in recent years have fled Venezuela's economic implosion by crossing into Colombia. Under a scorching sun, those in attendance waved Venezuelan flags, squirted water at each other and swayed to music by marquee artists including Colombia's Carlos Vives and Mexican rock band Mana as well as a host of Venezuelan performers.

Reymar Perdomo, a Venezuelan street singer who rose to fame for a video went viral showing her singing on buses in Peru, kicked off the concert with her signature song, "Me Fui," Spanish for "I left," which has become the unofficial anthem of the mass exodus.

Perdomo said performing so close to the border brought back painful memories.

"A little over a year ago I crossed this border and was robbed of my luggage and all my money," she said. "But I know in this moment that there will be change because Venezuelans want it and they are showing it today."

The plan to bring in aid is the most ambitious -- and potentially dangerous -- that the opposition has attempted to undertake since Guaido decided to challenge Maduro's rule.

But the embattled socialist has shown no signs of backing down, and analysts warn whatever happens over the next several days may not yield a conclusive victory for either side.

"I think one of the government's aims is to confuse the whole thing, possibly to create some kind of chaos that makes the opposition look bad," Phil Gunson, a senior analyst with the International Crisis Group based in Caracas, said of Maduro's rival concert. "It's a propaganda war."
