“I tend to spread positive energy,” Hassouna says. “But when the war started, there was no positive energy.”

His darkest hour came on Feb. 12.

The Israeli military unleashed heavy bombings to provide cover for commandos during a successful hostage rescue mission. At least 74 Palestinians were killed in that bombing campaign, according to Gaza health officials.

Hassouna’s mother, father, brother, sister-in-law and young nieces and nephew were among them. They were killed as they slept in the home where they were sheltering. It was the one night Hassouna happened to sleep over at a friend’s house.

“Now I am by myself,” he says. “Why should I live my life without a family?”
