Heartbreaking video shows tattoo artist Shani Loukjoyfully dancing at an Israeli music festival before she was stripped naked and paraded by Hamas terrorists — as her mom revealed Tuesday that she now believes she’s still alive.

The 23-year-old woman — who spent part of her childhood in Portland, Oregon — is seen in a new clip online dancing joyously at the Tribe of Nova event in the Negev Desert as she is surrounded by fellow revelers a short time before the massacre, which left at least 260 people dead.
