Soldier segregation
Col Richard Kemp, a former commander of British troops in Afghanistan, told the BBC it was important to remember that this was an isolated incident and "not a pattern of events".
He said: "The sort of thing you could do is to not allow Afghan forces to be armed with live ammunition in the same base as British troops unless they're about to go out on patrol but that would severely undermine trust.
"You could segregate bases between the two but that would not only undermine trust but it would also prevent the essential partnering that's taking place."
Maj Gen Patrick Cordingley, a former commander in the first Gulf War, told the BBC feelings would be "running high" over the next few days, "not only among the soldiers involved but also in this country, where people are going to continue to ask the question 'Is it all worthwhile?'"
He added: "It is this whole business now of trying to overcome the problem, and not let feelings run high, and trying to work out if there are some rogue elements in those soldiers and policemen who they're trying to train, but that's going to be difficult if you don't speak the same language."
