Despite media reporting that she was beaten by Hamas, Argamani went to social media on Friday to say that her words had been taken out of context. She said she was not beaten and her hair was not cut.
“I said, I had cuts all over my head and I was hurt all over my body.” Argamani emphasized that her wounds came from the collapse of a building after it was bombed by the IAF.
“As a victim of October 7, I will not allow myself to be victimized once again by the media,” she said.
