 The ambush was dispersed by back-up UN forces retaliating with heavy fire from Danish Snow Leopard tanks in two separate firefights.While no Danish or Swedish soldiers were killed in the operation, estimates place the number of Serbian casualties as high as 150.The incident is the first time Danish Armed Forces had carried out combat operations since the Second World War nearly fifty years prior, and is the source of ongoing debate and controversy as to the rights of UN peacekeeping forces to exert force and engage in direct combat.
