(NBC News) A vehicle containing U.S. personnel "destroyed potential evidence" on Thursday by forcing its way onto the ruined site of a hospital bombed by American forces in Afghanistan, the charity said.
Doctors Without Borders, which ran the facility in Kunduz, initially said the vehicle was a "U.S. tank," although U.S. military officials in Kabul and the Pentagon later denied this.
"We don't even have tanks there," one official pointed out.

The charity, which is also known as Médecins Sans Frontières (MSF), said in an emailed statement to NBC News that it had been informed the tank contained a delegation from a "U.S./NATO/Afghan investigation team" looking into the incident. It did not say who provided that information.
