A 9-year-old Irish-Israeli girl whose father first believed she had been killed on Oct. 7, was among the 13 Israeli hostages released on Saturday by Hamas. 

Emily Hand spent "her birthday in the tunnels of Gaza" her father told Fox News Digital last week. "No party. No friends. She won’t even know if it’s day or night. There’s no light down there. So she won’t know it’s her birthday." 

After waking up at a friend’s house in the kibbutz of Be’eri in southern Israel on Oct. 7, Hand, her friend, Hila, and her friend’s mother, were all kidnapped by Hamas terrorists. Hand was still wearing her Disney pajamas.

Hand’s release came a day after another group of 13 hostages were let go Friday, the first day of the temporary ceasefire. 

Thomas said he was first told his daughter had been killed before he realized she had been kidnapped. 

Before her release, her father last saw Emily the evening of Oct. 6 at dinner in the communal dining room of the kibbutz.

The IDF released a photo of Emily Hand, 9, and her father meeting again after Emily was kidnapped and spent 50 days as a hostage under Hamas terrorists.

"We had an eyewitness seeing her being led away by the terrorists with her friend where she was doing a sleepover and the mother of that friend," he said last week. "So it's absolutely confirmed that she was taken away by the terrorists and is in the tunnels of Gaza now."
