(Miami Herald) – A month after a U.S. AC130 aircraft raked a Doctors Without Borders trauma hospital in Afghanistan with canon fire, killing 30 including a dozen staff members, there is still no official U.S. report on what the United States believed led to the assault. But in the time since the attack, other medical facilities have been targeted in a range of conflicts around the world, heightening growing concerns among humanitarian workers that the long tradition of sanctity for hospitals, clinics and medical workers in combat zones has vanished in an era of scorched-earth combat.
