A citizen arrives to cast her ballot during a national election, the first in Europe since coronavirus lockdown, at a polling station in Belgrade, Serbia. The Western Balkan nation's voters are choosing their representatives in the 250-seat National Assembly. The balloting was originally scheduled for 26 April, but it was postponed due to the state of emergency declared in a bid to contain the spread of the ongoing pandemic of the COVID-19 disease caused by the SARS-CoV-2 coronavirus.
