The Israeli soldiers stormed the building. “They banged on our door. My husband … told them we are all civilians. They took him to another apartment. I followed them, pleading with them to let him go because we are civilians,” she said.

“They beat me and my daughters. They put us women in one place and threatened us with guns and knives. They made us strip. They searched us, insulting us using the most terrible words,” Salem added.

The soldiers disregarded their pleas and proceeded to “execute” all the men they rounded up outside.

“My husband was one of the 19 men killed in this building. They ordered them to bend down and executed them. They killed them all.”

The footage shows the bodies of men with the entry holes of bullets in their back.

After the men were killed, the apartment that Salem and her daughters were sheltering in was hit, one of her daughters told Al Jazeera, killing her three-year-old sister, Nada.

“I was holding my sister in my arms. Then the shelling resumed. Nada was hit. She made some soft sounds. She asked for some water.”

“I thought she was crying. But she was dying. Shrapnel had entered her head, eyes and neck. My sister tried to carry her body but she fell from her arms at the door.”
