Prosecutors in Milan have opened an investigation into Italian tourists who allegedly paid £70,000 to shoot innocent people in 'human safari' hunting trips to Sarajevo, with extra charged to kill children.

The wealthy foreign gun enthusiasts are accused of travelling to the city for 'sniper tourism' during its four-year siege in the 1990s by Serb-Bosnian militias amid the Bosnian War. 

Between 1992 and 1996, more than 10,000 people were killed in Sarajevo by shelling and sniper fire in the longest siege of a capital city in the history of modern warfare.
