A man is detained by police during a protest against the government in San Cristobal January 15, 2015. Masked youths are once again blocking streets and burning tires in the Venezuelan city of San Cristobal, epicenter of last year’s massive anti-government protests. The groups are small and the unrest contained, but tensions are unmistakably rising in this scarcity-ravaged Andean city close to the Colombian border. Picture taken January 15, 2015.
