It has been reported that Israel is again negotiating with Hamas for a prisoner exchange. It remains uncertain whether the three Israelis — Avera Mengistu, Hisham al-Sayed and Jumaa Abu Ghanima, all of whom are believed to have entered Gaza of their own accord and allegedly suffer from mental illness — are still alive. Hamas has refused to provide video documentation though Israel offered to release several Palestinian prisoners in return. Israel also seeks the remains of Lt. Hadar Goldin and Staff Sgt. Oron Shaul — two IDF soldiers killed in Gaza in 2014 — to give them an honorable burial and closure for their families.
