Israel is concerned that Hamas may kill hostages in retaliation for the death of its leader Yahya Sinwar. Security consultations have been held to prevent revenge killings, and Israel has issued warnings to protect the hostages. The hope is that Sinwar's death, which was accidental rather than a planned assassination, will reduce the motivation for harm. Talks for a hostage deal and ceasefire in Gaza may have to wait until Hamas selects new leadership. Israel is considering using Sinwar's body as a bargaining chip in negotiations, but is also concerned about it becoming a shrine for his supporters.
