Police have fired tear gas and clashed with protesters in central Belgrade, as tens of thousands gathered to demand early elections and an end to the more than decade-long rule of Serbia's populist President Aleksandar Vucic.
On Saturday, people crowded into Slavija Square, one of the capital's main junctions, in a fresh eruption of demonstrations that started a year and a half ago when a deadly roof collapse triggered a youth-led movement against alleged corruption and mismanagement.
Officers in riot gear cordoned off Belgrade city hall, about a kilometre away, before sporadic clashes broke out between protesters and police near the presidency building and outside a park where Vucic's supporters have been camping since March last year.
