Hamas, Israel in Egypt for mediated discussions on prisoner release
Hamas insiders informed Haaretz that its representatives are in the Egyptian capital after this was suggested by Cairo's intelligence.
They explained that the group's military second-in-command, Marwan Isa, plus high-level figure Rawhi Mushtaha are there on its behalf.
The insiders told the Israeli daily there have not yet been any significant developments.
The Palestinian faction has two Israelis prisoner, Avera Mengistu and Hisham Al-Sayed.
Neither of the men is in the military, though Hamas also has the corpses of Oron Shaul and Hadar Goldin.
Shaul and Goldin both died during a serious escalation in Gaza in 2014.
Gaza's rulers wish to keep the matter of the prisoners and dead soldiers apart from discussions relating to rebuilding efforts in the Strip, Haaretz reported.
The Palestinian enclave was heavily bombed during a deadly 11-day campaign carried out by Israel last month, while Hamas and other militants fired rockets at Israel.
In Israel, rocket fire from Gaza militant groups caused 13 deaths.
Last September, Israel decided to withhold the bodies of any Palestinian fighters killed in an anti-Israel attack from their families.
Palestinian legal NGO Adalah described this as "extreme, barbaric" and "illegal".
