Activists face National Guard troopers in riot gear during a protest in San Cristobal, capital of the western border state of Tachira, Venezuela, on February 21, 2014. At least 25 people were injured in late Saturday clashes with security forces that were some of the most serious to date. Venezuela’s president on Sunday called for crisis talks in an attempt to defuse weeks of often deadly anti-government protests that have brought the biggest challenge yet to his regime.
