Hamas's version of the story, aka the truth that will probably be backed up by multiple videos within 48 hours:

Martyr Izz El-Din Al-Qassam Brigades:
—
Al-Qassam fighters were able this morning to raid a newly established enemy position southeast of Khan Younis city in the southern Gaza Strip with an Al-Qassam infantry force.

Al-Qassam fighters stormed the position and targeted a number of Merkava 4 guard tanks with several Shuath explosive devices, guerilla explosive devices, and Al-Yassin 105 shells.

Al-Qassam fighters also targeted a number of houses where occupation soldiers were fortified, hitting them with 6 anti-fortification and anti-personnel shells and machine gun fire. A number of fighters stormed the houses and eliminated a number of occupation soldiers inside at point-blank range with light weapons and hand grenades.

Al-Qassam fighters also managed to snipe a Merkava 4 tank commander, inflicting a fatal injury. Our fighters shelled the surrounding positions of the operation site with several mortar shells to cut off reinforcements.

The operation site was also shelled with several mortar shells to secure the withdrawal of the fighters from the area. Immediately upon the arrival of the rescue force, one of the martyrdom-seekers detonated himself among the soldiers, causing casualties between killed and wounded. The attack continued for several hours, and our fighters observed helicopter landings for evacuation.
