University students in Serbia launched a 24-hour blockade of a main street in Belgrade during New Year's holiday rush. They set up a makeshift camp near the government headquarters, protesting irregularities in the recent election. The students triggered a traffic gridlock and plan to continue their protest until an opposition gathering on Saturday. Political tensions are high in Serbia, with the opposition alleging fraud in the election. The opposition alliance, Serbia Against Violence, has been leading daily protests and calling for fair elections.
