Eyewitness says American subcontractors at Gaza aid sites fired at Palestinians

Since the Gaza Humanitarian Foundation first began operating nearly three months ago, the U.N. says hundreds of Palestinians have been shot and killed by Israel Defense Forces and foreign military contractors at or near its aid sites. CBS News spoke to a new eyewitness who said it's not just the IDF firing at Palestinians, but also personnel hired through American subcontractors to secure GHF sites.
