Three British troops killed by a U.S bomb?

Times like this one will surely be excused for feeling like thumping someone.it is bad enough that the militants are taking every chance to take pot shots at the allied forces in Iraq and Afghanistan.but to make huge mistakes like this which has resulted in the death of three people who were there to uphold the peace and stability and to protect the innocent Iraqi citizens.well,with mistakes like this i do not think that we need the militants to kill any troops since we are doing such a good job of it ourselves!
