Despite no substantial evidence of any military activity conducted under hospitals having been presented, the IDF is continuing with its attacks, postponing a humanitarian pause agreed upon on Wednesday.
Tunnels are reportedly used for smuggling supplies, and also serve as underground networks for the swift movement and evacuation of fighters and equipment, the operation of underground command posts, and even workshops for weapons production.
The extent of the tunnel network is significant, with Hamas Political Bureau chief Ismail Haniyeh boasting in 2018 that it was two times bigger than the legendary Cu Chi tunnels used by the Viet Cong during the Vietnam War.
The IDF's ground operation in Gaza's urban areas is largely hindered by the existence of these tunnels.
