Serbian President Aleksandar Vucic says it is unlikely there will be a long-weekend curfew in Belgrade. It follows overnight protests in the capital after he announced a possible lockdown.
Mr Vucic says the final decision will be made tomorrow by Prime Minister Ana Brnabic and Health Minister Zlatibor Loncar.
He asked protesters to stay at home to prevent the spread of coronavirus - and blamed right-wing extremists for the violent scenes at the National Assembly. Opposition parties had announced plans for another protest this evening.
Serbia has reported 341 new cases of Covid-19 in the past 24 hours.
Protesters gathered to voice anger against stricter lockdown measures that will come into force this weekend.
