The visit comes in response to an invitation from Egypt.

The discussions will deal with means of stopping the Israeli war on the Gaza Strip  -- now entering its 79th day --  and measures needed to reach a new deal on a captive-prisoner swap, a prominent source within the movement said.

The delegation will present the PIJ's vision for stopping Israeli aggression, withdrawing the Israeli forces from Gaza, and reconstructing the war-ravaged strip.

The source also noted that the PIJ’s delegation stressed that any deal to exchange Israeli captives for Palestinian prisoners must adhere to the principle of "all for all" and will be carried out, following a ceasefire, through a political process agreed upon with various political forces representing the Palestinian people.

Nakhaleh's visit comes three days after a delegation headed by Ismail Haniyeh, the head of Palestinian movement Hamas, arrived in Cairo for talks on ceasefire efforts with Egyptian officials.

Egypt and Qatar helped mediate a week-long cease-fire in November, in which Hamas freed over 100 captives in exchange for Israel's release of 240 Palestinian children and women detainees.

On Friday, the United Nations Security Council approved a much-delayed resolution to bring more aid into the blockaded Gaza Strip by ensuring "safe and unhindered delivery of humanitarian assistance at scale."

The resolution also called for creating "conditions for a sustainable cessation of hostilities" without calling for an immediate end to the fighting.

Since the beginning of its bloody war on Gaza in 7 October, Israel has killed over 20,000 Palestinians, including women and children, and wounded thousands of others.
