On October 7th, Hamas kidnapped Ofer Kalderon and his two kids. The children have since been released, but their father remains in captivity. "We're doing whatever we can, whatever we think can help to bring him back home. So, I'm here now. I came to Colorado, I came to the United States, to ask people: Help us," Sharon Kalderon, Ofer's sister in-law told 9NEWS. The kids were released in an earlier deal, after 52 days. "They're not okay. I don't know if they'll be okay some day," Sharon said, "But they cannot start healing without their father."
