BBC assesses footage of hostages and tunnels released by Israel
BBC Verify has been analysing footage released by the Israeli military on Sunday, showing a tunnel leading to a blast-proof door underneath the al-Shifa hospital complex in Gaza City.
They also released CCTV footage which they say shows two of the hostages abducted by Hamas being brought to the hospital.
Hamas has denied Israeli allegations that it has a command centre at the hospital.
