Members of the police forces of the Republic of Srpska march during a parade marking the 32nd anniversary of the Republic of Srpska, in the Bosnian town of Banja Luka, 240 kms northwest of Sarajevo, Tuesday, January 9, 2024. The United States on Tuesday warned that ongoing celebrations of a Bosnian Serb self-proclaimed national holiday were in violation of Bosnia's constitution and a 1995 peace agreement, and as such amounted to a criminal offense. The Jan. 9 holiday commemorates the date in 1992 when Bosnian Serbs declared the creation of their own state in Bosnia, igniting the country's devastating four-year war that killed more than 100,000 people.
