Serbian university students have left piles of old school books outside the education ministry building as part of daily street protests demanding accountability over the collapse nearly two months ago of a concrete canopy that killed 15 people in the country’s north.

This footage illustrates a huge crowd of people who gathered at Slavija Square in Belgrade, Serbia to protest against President Aleksandar Vucic and his ruling Serbian Progressive Party, whom they blame for roof collapse at a railway station on November 1 that killed 15 people.
