BBC Verify has been analyzing footage released by the Israeli military on Sunday, showing a tunnel leading to a blast-proof door under the al-Shifa hospital complex in Gaza City.
They also released CCTV footage which they say shows two of the guards abducted by Hamas being taken to hospital.
Hamas has denied Israeli allegations that it has a command center at the hospital.
