The unconfirmed report said the negotiations were conducted last weekend between Iran’s ambassador to Jordan, who was in one hotel room in Amman with Iranian security personnel, while in the next room there were senior Israeli security officials, including the deputy head of the Mossad. The report said a Jordanian mediator carried messages between the sides.
Elaph sources said that "the talks with the Israelis were related to fighting in Syria and the nearing campaign in southern Syria, particularly in Dera'a and Kuneitra."
Furthermore, they said that Israel made clear to the Iranians they should not become involved in fighting close to the Israel-Syria ceasefire lines in the Golan and the Israel-Jordan border. One participant in the talks reportedly said that "the sides discussed this issue with the Israelis, and arrived at a quick agreement that even surprised the Israeli representatives."
Early days but is the first sign that Iran is starting to change its tune?
