On 27 April 2015, a local gunman, shouting "Allahu Akbar", attacked a police station in Zvornik in the Republika Srpska entity of Bosnia and Herzegovina. He killed one police officer and wounded two others before he was shot dead by other police officers. This was the first attack of its kind in Republika Srpska, though similar ones have occurred in the other entity, the Federation of Bosnia and Herzegovina, including the 1997 Mostar car bombing and the 2010 Bugojno bomb attack on a police station in central Bosnia as well as an attack on the U.S. embassy in the capital Sarajevo a year later. The authorities of Bosnia and Herzegovina on each level characterised the shooting as a terrorist attack.
