Israel's army on Sunday published video that it says shows forces operating in the southern Gaza Strip city of Khan Younis and uncovering mortars and other munitions.

The video, which mostly appeared to be taken by a bodycam located on one of the soldiers, shows gunbattles and explosions as well as soldiers entering buildings through holes in the exterior walls of the building.

Reuters was not able to independently verify the location nor the date the video was taken.

Sunday marked 100 days after Hamas gunmen broke out of Gaza to launch the deadliest attack in Israel's history, killing more than 1,200 and kidnapping 240 others into Gaza, mostly civilians.

As the war that Israel launched with the aim of annihilating Hamas wages on, almost 24,000 Palestinians have been killed, Gaza lies in ruins, and the Middle East is sliding toward a wider, more unpredictable conflict.

For both Israelis and Palestinians, the war has been a trauma that looks likely to last for years, deepening the hostility and mistrust that have stood in the way of peace for more than 75 years.

Three months on, Israeli troops are still battling Hamas militants in the ruins of Gaza and hunting architects of the October attack, such as Yahya Sinwar, the Hamas leader in Gaza, and Mohammed Deif, the movement's military leader.
