After the Christmas holidays and New Year German mediator, Gerhard Conrad, returned to Gaza through Rafah crossing .The mediator, is scheduled to meet with Hamas heads Dr. Mahmoud al-Zahar and Dr. Khalil al-Haya, in order to receive Hamas' position towards a prisoner exchange deal between Israel and Hamas. As reported in recent days, the movement is expected to present its reservations regarding the Israeli offer, but is unlikely to shut the door on the continuation of talks. Palestinian sources said that Hamas plans to stress to the mediator that it does not accept Israel's stance: "The Hamas delegation will clarify that it rejects the Israeli response, but will also stress that, with all its reservations regarding the Israeli document, it is still willing to keep negotiations going towards solving the issue."
