(ANSA) - BELGRADE, 01 NOV - Bosnian police arrested a 28-year-old Islamist extremist near Sarajevo, who called to kill policemen through messages on Facebook and TikTok. Regional media report that the arrest of the young man - identified as Osman Malagic - took place yesterday at the request of the prosecutor's office of Bosnia and Herzegovina. One week ago a 15-year-old Islamic extremist broke into a police station in Bosanska Krupa, north-west Bosnia and Herzegovina, stabbing one policeman to death and seriously wounding another. Eight people were arrested, as they were considered to be close to Islamic radicalism and involved in the attack by the 15-year-old. (ANSA).
