Student-led protests in Belgrade are escalating, with demonstrators demanding early elections in Serbia. The protests follow months of nationwide rallies against President Aleksandar Vucic's government. Organizers have issued an ultimatum to Vucic, threatening a campaign of civil disobedience if their demands are not met. The situation remains tense as the government has yet to respond to the ultimatum or address the protesters' concerns. The protests highlight growing discontent with the current political climate and economic conditions in Serbia.
