The mother of one of the four Hamas hostages rescued by Israeli forces during a special operation over the weekend says her son has described to her "very strange rules" the Palestinian terrorists made him live by. 

Evgeniia Kozlova told Reuters that her first conversation with Andrey Kozlov after he was freed was "both hard and joyful, and wonderful, and terrible because he was in a huge emotional turmoil." 

"He told us that they were required to follow some very strange rules, like you can't sit with your legs towards these terrorists. You can't do this, and you can't do that," she said to the news agency. "You could be punished for getting the wrong water or getting it from the wrong place." 

"They liked to tell them: 'You're an animal, you're a donkey, you're a fool, you're dirty," Kozlova also recalled her 27-year-old son as saying. "Andrey now knows these words perfectly well in Arabic, everything about Arabic swear words he has learnt well."

Kozlova added that "Andrey told us: 'There are some things I will never tell you'. I don't know what he didn't tell us and what he doesn't want to ever tell us." 

She told Reuters that her son – who was captured by Hamas at the Nova music festival near the Israel-Gaza border on Oct. 7, 2023 – said he remained convinced he would return to Israel at some point. 

"There was such a flow of energy from him, he was crying and laughing, and I was laughing too. We were comforting each other," Kozlova said.
