Palestinian terrorist group Hamas announced the names on Friday of four Israeli women soldier hostages to be released in exchange for Palestinian prisoners in the second swap under the ceasefire deal in Gaza.

Karina Ariev, Daniella Gilboa, Naama Levy, and Liri Albag would be released on Saturday, the group said.

The exchange, expected to begin on Saturday afternoon, follows the release on the ceasefire’s first day last Sunday of three Israeli women and 90 Palestinian prisoners, the first such exchange for more than a year.

Prime Minister Benjamin Netanyahu’s office confirmed that the list had been received from the mediators. Israel’s response would be presented later, it said in a statement.

Israeli media reported that the list of hostages slated for release was not in line with the original agreement, but it was not immediately clear whether this would have any impact on the planned exchange.

Later on Friday, a Hamas official told Reuters Israel had asked through the mediators that the group replaces one of the soldiers, Albag, with a female civilian, Arbel Yehoud.

Asked why the switch had been requested, he replied: “It is technical and has to do with the situation in the field,” without elaborating.

In the six-week first phase of the Gaza ceasefire, Israel has agreed to release 50 Palestinian prisoners for every female soldier released, officials have said. That suggests that 200 Palestinian prisoners would be released in return for the four. The Palestinians slated to be released from Israeli jails were largely detained for involvement in terrorist activities.

The Hamas prisoners media office said it expected to get the names of 200 Palestinians to be freed on Saturday in the coming hours. It said the list was expected to include 120 prisoners serving life sentences and 80 prisoners with other lengthy sentences.

Since the release of the first three women on Sunday and the recovery of the body of an Israeli soldier missing for a decade, Israel says 94 Israelis and foreigners remain held in Gaza.

The ceasefire agreement, worked out after months of on-off negotiations brokered by Qatar and Egypt and backed by the United States, halted the fighting for the first time since a truce that lasted just a week in November 2023.

In the first phase, Hamas has agreed to release 33 hostages in exchange for hundreds of Palestinian prisoners held in Israeli jails.

In a subsequent phase, the two sides would negotiate the exchange of the remaining hostages and the withdrawal of Israeli forces from Gaza.

Hamas started the war when it led an invasion of and massacre across southern Israel on Oct. 7, 2023. During the onslaught, Palestinian terrorists murdered 1,200 people and kidnapped 251 hostages. Israel responded with a military campaign aimed at freeing the hostages and dismantling Hamas’s military and governing capabilities in neighboring Gaza.

The release of the first three hostages last week brought an emotional response from Israelis. But the phased release has drawn protests from some Israelis who fear the deal will break down after women, children, elderly, and ill hostages are freed in the first phase, condemning male hostages of military age whose fate is not to be resolved until later.

Others, including some in the government, feel the deal hands a victory to Hamas, which has reasserted its presence in Gaza despite vows of Israeli leaders to destroy it. Hardliners, including Finance Minister Bezalel Smotrich, have demanded that Israel resume fighting at the end of the first phase.

Most of Hamas‘s top leadership and thousands of its fighters have been killed but the group’s police have returned to the streets since the ceasefire.
