(CNN) Thousands of people gathered in Slovakia's capital city Friday night to protest against the government and pay tribute to murdered Slovak journalist Jan Kuciak.

Prime Minister Robert Fico resigned Thursday after weeks of public protests over the slaying of the investigative journalist and his fiancée, Martina Kušnírová, who reported on fraud among the country's elite -- but many Slovaks are not convinced the desired political change will follow from Fico's departure.
