Rogue U.S. soldier kills 15 civilians in Afghanistan.

"He reportedly left his military base in the early hours of the morning, attacking at least two homes. Nine children are among the dead."

The soldier - who reportedly suffered a breakdown before the attacks - is said to have handed himself over to the US military authorities after carrying out the killings....

"This is going to have very, very bad effect, I believe, and I think it is time the US may have to alter their policy of not allowing their soldiers to be tried in foreign countries," [said Prince Ali Seraj, head of the National Coalition for Dialogue with the Tribes in Afghanistan].
