(Update1720ET): Hamas has released a hostage 'proof of life' video which is now being widely shared online and reported on, per Israeli media: 

The short video shows a young woman, 21-year-old Mia Schem, being treated after she was wounded in her arm, and later speaking to the camera.

Schem was kidnapped by Hamas terrorists on October 7 while taking part in the desert rave in Kibbutz Re'im, where the gunmen also massacred over 260 festival-goers.

She tells the camera she was operated on for three hours and that "I'm being cared for, I'm getting medications. I'm only asking for me to be returned home as soon as possible, to my family, to my parents, to my siblings. Please get me out of here as soon as possible." Schem's family reacts to the clip, saying: "We're happy."

The IDF has reacted to the video, saying Hams "tries to present itself as a humanitarian organization while in fact it is a murderous terror group, responsible for the murders and kidnappings of babies, women, children and the elderly."

There's growing speculation that the IDF hasn't launched a ground invasion yet due to threats being made by Iran and its ally Lebanese Hezbollah. And it's not just enemies of Israel that are saying this, but The Jerusalem Post reports Monday that a prime reason for the offensive being stalled is the fear Hezbollah will get involved.
