Serbia’s striking students and supporters of populist President Aleksandar Vucic have planned parallel rallies on Saturday as both mark the country’s Statehood Day with notably contrasting messages.

The student-led protest is the latest in a nationwide anti-graft movement that reflects mounting calls for fundamental political changes in the Balkan state, triggered after a concrete canopy collapsed on a railway station in the northern city of Novi Sad on November 1, killing 15 people.
