Serbian students march into Belgrade for a final rally while populist Aleksandar Vucic rallies in the south before the vote

Serbia's student protest movement concluded its campaign with a mass rally in Belgrade on the eve of a pivotal election. Populist president Aleksandar Vucic, whose Serbian Progressive Party is facing the youth-led challenge, held a rival rally in the south of the country.

Serbian authorities arrested six individuals on suspicion of planning violence on election day.

Additional arrests were reported across Serbia in the days leading up to the poll.
