The Red Cross wants to have a greater influence in the virtual world of battlefields.
The aid organisation is arguing that as virtual war games are becoming close to reality, the rules of war should be included.
It claims games such as Medal of Honour, or Call of Duty should make sure that actions which could be war crimes are not rewarded with victory in a virtual battle.
