Israel Discovers Hideout of Hamas Terror Chief Built Over Massive Secret Tunnel System, Destroys Both

Hamas terror chief Yahya Sinwar, who has a $400,000 bounty on his head, was nowhere to be found — but a 'very significant' tunnel system was

Israeli troops uncovered and destroyed a Gaza hideout used by wanted Hamas terror chief Yahya Sinwar , as well as a “very significant” attached tunnel system outfitted with electricity, ventilation and sewage systems, the Israel Defense Forces said Friday.

The IDF detailed the recent discovery along the outskirts of Gaza City with a series of videos, including aerial footage of the complex being demolished with a massive explosion.

Troops first discovered and raided the apartment used by Sinwar, one of the most wanted Hamas leaders with a $400,000 bounty on his head.

Though they did not find Sinwar, they did discover a shaft in the basement floor leading to a branching tunnel system approximately 715 feet long and 65 feet deep, believed to have been used by senior Hamas leaders, the IDF said.

Video shot by an Israeli robot deployed into the system shows just some of its winding pathways and high ceilings.

The subterranean network was equipped with electricity, ventilation and sewage systems, as well as prayer rooms, suggesting that it was built with long-term use in mind, the IDF said.

“We found a very significant Hamas tunnel system," said the commander of the IDF’s 14th Brigade, who was not identified by name. "The system is deep, much deeper than the other systems."

After the IDF swept the apartment and the tunnels, they destroyed both with a massive blast that sent plumes of dust and debris into the air.

The IDF last week detailed the discovery and destruction of tunnels linking the homes of top Hamas figures in Gaza City.

Entrances to similar systems dot Gaza, with some hidden among civilian targets for the perceived cover such sensitive positions provide, according to the IDF.

Israel has used robots and explosive gels to trim the tunnel system from the surface and avoid venturing into its dark and winding corridors, where Hamas holds a defender's advantage.

Earlier this month, Israel reportedly began flooding some tunnels with seawater in an attempt to flush out Hamas fighters.

That tactic went into action over objections from the families of some Hamas hostages believed to be held underground.
