Edan Alexander, the last living American held hostage by Hamas, was finally freed from Gaza Monday

Edan Alexander, the last living American held hostage by Hamas, was finally freed from Gaza Monday after enduring more than 19 months of unimaginable horror at the hands of the depraved terror group.

The 21-year-old Israeli-American citizen from New Jersey was emotional as he reunited with his family, tightly embracing his mother Yael and his younger brother following his 584 days in captivity.

Meanwhile, harrowing details of his time spent in Hamas’ clutches were revealed Monday — he was severely tortured and often locked in a cage, shackled at the hands and feet, deep within the terrorists’ underground tunnel network, according to the Kan public broadcaster.

Severely malnourished and weak on his feet, Edan was turned over to the Red Cross and then to Israeli forces before crossing back into the Jewish state Monday evening local time, the Israeli military said.

His long-awaited homecoming celebration kicked off before he was even en route.

Moving video released by Israel Defense Forces showed his mother, Yael Alexander, speaking to her son via phone just moments after he was freed, as overjoyed family members looked on with relief and delight.

“You are strong. You are safe. You are home. We’ll see each other soon. I love you,” Yael told her IDF staff sergeant son.

“You’re out, my dear. That’s it. I’m here waiting for you. Everything’s OK, you’re OK. You’re safe and you’re home, we’re going to meet soon. I love you, my dear,” she said, according to an IDF translation shared on social media.

Yael had received no indication her son was still alive — the last time she saw his face was when he was featured in a sickening propaganda video released by Hamas last month at the start of Passover, mocking the freedom-themed Jewish holiday.

Edan’s emotional extended family cheered and chanted as they gathered in Tel Aviv and his hometown in Tenafly, NJ, to watch his televised release, wearing shirts emblazoned with his name.

A photograph broadcast by Al Jazeera TV showed Alexander – dressed in a black Adidas t-shirt and black baseball cap — standing next to masked Hamas fighters and a Red Cross official shortly before the handover.
