Hamas chief Yahya Sinwar was prepared to hide out the war in his secret bunker beneath Gaza flushed with UN food rations, thousands in cash, cologne and his own shower, Israeli officials say.

Footage from the Israeli military gives a peek into how the Oct. 7 mastermind spent his days in Khan Younis during the first half of the war — before he was forced to flee to Rafah, where he was killed last Thursday.

The resurfaced video from February depicts a bright and cozy living quarters for Sinwar, 61, and his guards, with a fully stocked kitchen that Israeli Defense Forces officials said would help the terrorists ride out the war decimating Gaza above ground.

The soldier giving the tour, who was not named, showed off a bag of food with the label of the embattled United Nations Palestinian refugee agency (UNRWA) group.

Hamas has been repeatedly accused of stealing rations from the international agency, which hands out supplies to Gaza’s nearly two million refugees.

Israel has also accused the UNRWA being infiltrated by Hamas, allegations that the group denies despite firing nine staffers after a probe linked them to the Oct. 7 terrorist attack.

Along with the cache of food, the soldiers found several bathrooms and showers in the bunker that were notably cleaner and more modern than other baths found in Hamas’ tunnel system.

Further inside were the living quarters of Sinwar’s bodyguards, with lockers next to the door housing a cache of weapons, ammunition and explosives.

At the back of the bunker was a small room reserved for the Hamas chief, with a large safe beside his bed containing “millions” of shekels — the Israeli currency, according to the soldier.

“He lives here in a good way, with all his millions, while the civilians above ground are living in poverty and are starving,” the IDF soldier said.

The terror chief also appeared to have several bottles of cologne, hygiene supplies and tonics stored in his room.

Sinwar and Hamas’ other slain leaders have often been accused of living luxuriously in Gaza at the detriment of the people they were supposed to be governing. Their Khan Younis estates and vacation homes were the target of criticism when they were documented by the Israeli military last year.

During his family’s escape beneath Gaza on the eve of the Oct. 7 massacre, Sinwar’s wife, Abu Zamar, was allegedly holding a $32,000 Birkin bag, according to Israeli officials.

The IDF suspect Sinwar hid in the Khan Younis bunker as he directed Hamas’ forces in the first half of the war as the group’s Gaza leader.

The Israeli military surrounded Sinwar’s home in December and breached the bunker by February, just missing the terrorist and his men as they fled further south.

Sinwar was allegedly hiding out the remainder of the war in Rafah, where hundreds of thousands of Palestinian refugees fled to during the IDF’s southward advancements.

Despite his ability to repeatedly elude the IDF, Sinwar was caught by chance in a routine operation in Rafah, with IDF soldiers killing him in a missile strike suspecting he was just another Hamas fighter.

Officials believe Sinwar was attempting to free north as the IDF continued to hunt for him in Rafah.
