Relatives of hostages in Gaza are urging Israel to immediately begin the second phase of the hostage deal to ensure their loved ones' safe return. They are concerned that if Israel resumes fighting in Gaza before the hostages are brought back, they will not survive. The family members are calling for a stronger and safer deal, emphasizing the urgency of the situation. They point to the emaciated state of one hostage who was released during the first phase as evidence of the dire conditions faced by those still held captive.
