Harrowing new video captured the moment a Hamas terrorist and his unit celebrated invading Israel and killing an IDF soldier on Oct. 7 before being fatally shot himself.

The 100-minute-long bodycam recording, provided by the IDF to CNN, also offered a rare glimpse into Hamas’ 300-mile tunnel system beneath Gaza, showing off the terrorist group’s stash of supplies in the narrow passageways with the words, “What’s hidden is far worse” written in Arabic.

Above ground, the video follows a 24-year-old member of Hamas joining a group of men in pickup trucks and on motorbikes as they breach the border between Gaza and Israel while shouting, “Allahu Akbar.”

The terrorists can be seen outfitted with rifles and loads of ammunition, with some carrying multiple rocket-propelled grenades sticking out of backpacks flung on their shoulders.

The men appear less than coordinated as they drive around Israel before reaching a field near the town of Kissufim, where they begin a shootout with an IDF soldier.

The gunman with the bodycam rushes in, firing his rifle as he covers one of the terrorists carrying the grenades.

Spotting the Israeli soldier on the ground, the gunman fires multiple times at point-blank range, killing the Jewish soldier.

The gunman proceeds to steal the soldier’s Tavor rifle and celebrates the kill, posing for a selfie with his bodycam as the other terrorists join in and cheer him on.

Following the murder, the gunman appears much more composed than when the invasion began, touting his victory as he introduces himself to the camera.

He describes himself as a father and adds that he’s murdered two Israeli soldiers. He then asks God for a “well-deserved martyrdom.”

The Hamas unit’s celebration continues as they pass the bodies of Israelis sprawled across a street.

With the roads cleared for them by the first wave of Hamas, the group continues on to Kibbutz Re’im, where the gunman exits his vehicle to fire at an IDF soldier in the distance.

The gunman with the body camera shoots from outside the military base in the kibbutz before he pauses for a second.

At that moment, someone from the base fires back, hitting the gunman, who yells as he rolls on the ground.

The 24-year-old screams in shock and pain before his breathing starts slowing down and he ultimately dies, putting an end to his role in the terror attack.

While the one gunman died that morning, Hamas’ attack would continue for hours as the terrorists killed roughly 1,200 people in Israel on Oct. 7 and kidnapped nearly 240 others.

The attack triggered Israel’s all-out war against Hamas, with the IDF launching airstrikes and a ground invasion to destroy the terrorist group.
