CNN's story
Here is the link to cnn's story of the same action.
The marines were being fired upon from a wall several hundred yards away from the mosque.
It does not matter where you are firing from, fire will be returned.
Seems to me these combatants should have been killed.
Now the cnn story also states that women are now carrying weapons, so when the Marines kill them this will be a major story for the anti-war crowd.( women killed by US Marines!!!) oh the travesty!!!!
