The Israeli military is "fighting deep inside the Gaza Strip," killing "terrorists in close range combat" and "conducting coordinated strikes on terror targets from land, air and sea," the Israel Defense Forces said Tuesday.

The IDF said it has "eliminated many terrorists and destroyed terror infrastructure."

On Tuesday, Israeli soldiers killed terror leader Ibrahim Biari, the IDF said.

"Striking Biari caused the collapse of adjacent buildings because of the expansive infrastructure there whose purpose was to launch terror attacks against our forces," the IDF said. "During the battle, the entire infrastructure collapsed and many terrorists were killed."

"The Hamas terrorists continue to use civilian population as protective armor. This is intentional and devastatingly barbaric," the IDF continued. "Once again, today, we call on the citizens of Northern Gaza to move Southward. … We will act forcefully in the city of Gaza and in the Northern Gaza Strip. We will continue to act against any terrorist in every part of the Gaza Strip."

State Department spokesperson Matthew Miller signaled Tuesday that the U.S. might be close to securing safe passage for the approximately 400 Americans and 600 of their immediate family members trapped in Gaza, saying negotiators "have made good progress on this."

"We are making very good progress on this issue. You may have seen some reports that have moved from the region just in the last few hours about the possibility of Rafah gate opening tomorrow,” Miller said. "I'm not in the position to make any announcements as I stand here right now, but I would say that we would welcome any agreement that would permit the safe exit of American citizens, families, other foreign nationals."

The Rafah border crossing between Egypt and Gaza is expected to open Wednesday to receive injured Palestinians from Gaza, according to Egypt state-linked TV channels.

National Security Council spokesman John Kirby would not discuss the Israeli strike that hit Gaza's Jabaliya refugee camp on Tuesday, but he did say broadly that the U.S. believes Israel is "trying to minimize" civilian casualties in Gaza.

"It's obvious to us that they are, that they are trying to minimize,” Kirby said.

He said that assessment is based on the "daily conversation we are having with our counterparts about their goals, the strategies, and their plans."

"We’re not going to react to every event in real time, but will certainly recognize that civilians have been hurt, civilians have been killed, to the tune of many thousands, that infrastructure has been damaged by these airstrikes," Kirby said. "We’re not accepting of any single civilian death in Gaza. They’re all tragedies. And we continue to work … with the Israelis about the need to respect human life and to try to limit civilian casualties."

Following repeated warnings from President Joe Biden and his administration for Israel to follow the "rules of war," ABC News asked Kirby if a strike like this on a refugee camp would mean they violated that, but Kirby would not speculate on the explosion, saying he had no information on what occurred.

Hamas has released a new video that claims to show three female hostages. One of the hostages speaks in Hebrew pleading for their release, blaming Israeli Prime Minister Benjamin Netanyahu for Hamas' Oct. 7 attack and calling on Netanyahu to help free the hostages.

The group that represents the hostage families confirms the names of the three women in the video as Rimon Buchshtab Kirsht, 36; Danielle Aloni, 44; and Yelena (Lena) Trupanob, 50.

Netanyahu's office in a statement called the video "cruel psychological propaganda by Hamas-ISIS."

"We embrace the families and are doing everything to return all of the captives and missing to their families," Netanyahu's office said.

According to the Israeli military, 230 people were taken hostage by Hamas.
