Rand Paul backed calls for an international investigation of the U.S. military after American forces inadvertently bombed an Afghan hospital over the weekend.
The hospital was "mistakenly struck" during an American air strike on Saturday, killing 22, according to the U.S. commander in Afghanistan.
The U.S. and Afghan militaries have already launched their own investigations into the incident, but activist groups are calling for a separate probe by an "independent international body."
Paul said he had no problem with such an investigation during an interview with CNN’s Wolf Blitzer on Tuesday.
"You’re a physician, you’re a doctor," said Blitzer. "Do you agree with the executive director of Doctors Without Borders, that in addition to the U.S. investigation, the NATO investigation, the Afghan investigation, there should also be an impartial outside international investigation?"
"Yeah, I don’t mind an outside international investigation," said Paul.
He added that "somebody needs to step up and say why are we there and what is the policy" in Afghanistan.
"Doctors and hospitals should never be targeted, and so that is completely unacceptable," said Paul. "But if it is an accident, it is still bad policy, because why are we dropping bombs in Afghanistan?"
