CNN has obtained and verified several videos of the incident and has spoken with witnesses.
Videos show the commandos bodies strewn across an outdoor market.
After a fierce battle to hold the town, the commandos had run out of ammunition and were surrounded by the Taliban fighters, witnesses said.
In one video, about 45 seconds long, a bystander can be heard saying in Pashto, the local language: Don t shoot them, don t shoot them, I beg you don t shoot them.
The bystander then asks: How are you Pashtun killing Afghans? The Pashtuns are the main ethnic group in Afghanistan.
