Gaza war: How investigators would go about finding and verifying underground military complexes
Following the raid on the al-Shifa hospital in Gaza by units of the Israel Defence Forces on October 15, the IDF claims to have uncovered evidence of tunnels underneath the hospital. A video released on November 19 showed a tunnel running under the al-Shifa medical complex at a depth of ten meters, running 55 meters along to what IDF sources said was a blast-proof door.
