Salameh was by Deif's side, and according to the sources, his body was recovered and buried immediately.
Hamas later released a statement on its official Telegram channel denying the claims that the negotiations would "halt."
'Despite the attempted assassination, Hezbollah will not operate in a more significant way than it is currently', says Prof. Amatzia Baram.
Deif's survival up until this point shows that the damage has been done and cannot be reversed.
Commander of Hamas's Khan Yunis Brigade, Rafa Salama, was likely killed in the same strike, and no hostages were killed.
"Go forth, light and heavy, and strive with your money and your lives in the path of God," the Hamas leader added.
Issa was reportedly hiding in Nusirat, in central Gaza, at the time of the strike, and it is unclear whether the Hamas leader was killed in the event.
According to a report on Channel 13, Israel and the US have recently been discussing a plan for the exile of senior Hamas members as part of a wider deal.
According to some estimations, it is possible that Sinwar has surrounded himself with hostages, used as human shields.
Hagari also said that "Hamas's military framework in the northern Gaza Strip has been completely dismantled," and that the photo of Deif was found on a computer that was seized in the Strip.
