Investigation promised into Afghanistan massacre

The U.S. military is promising a full investigation and possible prosecution of the U.S. solider suspected of leaving his base in Afghanistan and proceeding to kill at least 16 civilians, including women and children. The Afghan parliament is calling for an open trial of the soldier.

U.S. President Barack Obama said the shootings had only increased his determination to get American troops out of Afghanistan.

However, Obama cautioned there should not be a "rush to the exits" for U.S. forces who have been fighting in Afghanistan since 2001 and that the drawdown set for the end of 2014 should be done in a responsible way.
