The CCTV video has a time stamp for Oct 7 and shows a group of armed men taking an injured man into the hospital and running through the halls.
Another angle shows a man bleeding on a stretcher being taken to a different room.
IDF spokesman Rear Admiral Daniel Hagari said on X, "In the documentation exposed with the assistance of the ISA, Hamas terrorists can be seen on Saturday, October 7th, forcibly transporting hostages, a Nepalese civilian and a Thai civilian, who were kidnapped from Israeli territory. These findings prove that the Hamas terrorist organization used the Shifa Hospital complex on the day of the massacre as terrorist infrastructure."
He continued, "These findings add to previous evidence presented regarding Hamas’ use of the hospital area as infrastructure for its terrorist activities in a systematic and ongoing manner."
Video was also released showing terror tunnels located as part of the hospital complex.
Hagari also announced on Sunday that a female IDF servicemember Noa Marciano, 19, who was kidnapped by Hamas terrorists on October 7, "…was taken into Gaza alive, she was held hostage by Hamas in Gaza City next to the Shifa Hospital."
"During ongoing combat, in the vicinity of where she was held captive, Noa’s Hamas captor was killed and Noa was injured."
Hagari added that Marciano's injuries were "not life-threatening" and that Hamas terrorists killed her inside the Al-Shifa Hospital. "Hamas terrorists took Noa into Shifa hospital where she was murdered quickly. Hamas murdered Noa inside Shifa hospital. Our thoughts are with Noa’s family. We send our heartfelt condolences to Noa’s family. We did not reach Noa in time."
On Friday, the body of another hostage Yehudit Weiss was also found at the hospital complex.
Hagari noted, "This has only made the IDF more determined to do everything, everything in our power, to bring all our hostages home."
