A ceasefire between Israel and Hamas went into effect on Friday.
President Donald Trump announced Wednesday that both Israel and Hamas had "signed off" on the first phase of a peace plan in Gaza following negotiations in the Egyptian Red Sea city of Sharm el-Sheikh. A ceasefire then came into effect on Friday.
Phase one of the deal will see all remaining hostages returned from Gaza, a number of Palestinian prisoners released from Israeli jails and the partial withdrawal of the Israel Defense Forces inside the strip.
The Israeli delegation for this week's ceasefire talks in Sharm el-Sheikh will depart for Egypt this afternoon, two sources familiar with the matter told ABC News on Monday.

Iran's Foreign Ministry on Monday expressed its "readiness to participate" in U.S. President Donald Trump's proposed Gaza Strip ceasefire deal, as negotiators gathered in Egypt for talks on its possible implementation.
Iran, which in June was attacked by both Israel and the U.S. in an intense 12-day conflict, has "hope for the immediate delivery of humanitarian aid to the oppressed people of Gaza," the statement posted to the ministry's official X account said.
Tehran said there was a "legal and moral responsibility of all governments to support the legitimate and lawful struggle of the Palestinian people to realize their right to self-determination and liberation from the yoke of occupation, apartheid and colonialism" by Israel.
Any end to the war "does not negate the responsibility of governments and competent international institutions to pursue legal and judicial action" against Israel, the statement said, "nor the identification and prosecution of those who ordered and carried out war crimes, genocide, and crimes against humanity in the Gaza Strip."
The ministry also said there are "dangerous dimensions and aspects of this proposal," warning of what it called "repeated breaches and obstructionism" by Israel in past ceasefire efforts.
U.S. President Donald Trump said in a post to social media on Sunday that there had been "very positive discussions with Hamas, and Countries from all over the World" on a proposed ceasefire in the Gaza Strip.
"These talks have been very successful, and proceeding rapidly," Trump added. Technical teams will meet again on Monday in Egypt "to work through and clarify the final details," the president said.
"I am told that the first phase should be completed this week, and I am asking everyone to MOVE FAST," Trump wrote.
