Israel-Gaza live updates: Hamas publishes names of 20 living Israeli hostages to be released

The Israeli government approved the first phase of the ceasefire deal at 1:20 a.m. Friday local time in Israel, triggering the next series of steps under the deal.

Here's a look at what happens next, according to Israeli sources and a draft document of the agreement obtained by ABC News.

The Israel Defense Forces will withdraw and redeploy troops to agreed-upon lines within 24 hours of the Israeli government approving the deal. This means that the IDF will reposition by 1:20 a.m. Saturday local Israel time. Once the IDF redeploys to the agreed upon borders, the IDF will remain in control of more than 50% of Gaza during this phase of the deal.

Within 72 hours after the IDF completes redeployment to the agreed-upon borders, all hostages, living and dead, will be released and returned to Israel.

In exchange, more than 1,000 Palestinian prisoners will be released. That includes 250 prisoners and detainees held in the custody of the Israeli Prison Service, along with 1,700 residents of the Gaza Strip who were not involved with the Oct. 7, 2023, attacks but were arrested afterward, according to a draft document of the agreement obtained by ABC News.

Under the terms called for in the first phase, more humanitarian aid will also be allowed into the Gaza Strip -- but details on when and how are still unknown.

The Israeli government has approved the first phase of the ceasefire deal that was agreed upon in Sharm El-Sheikh, Egypt, on Thursday, according to the Israeli Prime Minister's Office.

The ceasefire went into effect at 1:20 a.m. Friday local time.

This means the Israeli Defense Forces now have 24 hours -- until 1:20 a.m. Saturday local time -- to withdraw to the agreed-upon lines inside of the Gaza Strip.

U.S. Central Command is establishing a coordination center in Israel to support and monitor the ceasefire agreement between Hamas and Israel, according to a U.S. official.

The official stressed that no U.S. military personnel will be deploying to Gaza, but that 200 U.S. servicemembers will be operating from inside Israel.

In addition to monitoring the ceasefire, the coordination center will help with the flow of humanitarian, logistic and security assistance into Gaza, according to the official.

The U.S. military personnel will provide expertise in security, planning, logistics, engineering and transportation, the official said.

President Donald Trump said "nobody is going to be forced to leave" Gaza, clarifying disconnect between the 20-point peace plan and what he told reporters on Thursday.

"It's just the opposite. This is a great plan. This is a great peace plan. This is a plan that was supported by everybody," Trump said.

Earlier Thursday, he said, “you can't live right now in Gaza.”

When asked about the possibility of a Palestinian state, Trump said “we're going to see how it all goes” but that they might consider options that may be “a little bit different.”

“We're going to see how it all goes. And there's a point at which we may do something that would be a little bit different and may be very positive for everybody,” Trump said.
