A 50-year-old woman who has been a cancer patient for three years says she has not been able to receive her continuing treatment in Jerusalem since the war began, she told ABC News.

Rida Kaskeen, who now lives in a makeshift tent in Rafah, had received chemical treatment for her cancer in Jerusalem before the war began. But since it started, border closures have kept her from being able to get her treatment.

"I am a cancer patient. I used to go every two weeks to take my dose in Al-Mutalaa Hospital. They were all there with respect and appreciation. They provided me with everything, from a hotel or in the hospital, to everything I wanted and needed. They were doing their duty and more," Kaskeen told ABC News.

"My last dose was a week before the war. Every two weeks is the dose, and I have not taken the treatment for three months, and I know my end because I didn’t take the treatment and I lost weight and my situation is miserable,” Kaskeen said.

Hamas leader Osama Hamdan said he would not travel to Cairo on Friday to discuss its proposed cease-fire and hostage deal.

"There will be no visit by a Hamas delegation to Cairo today," Hamdan said.

Another Hamas leader said the terror group would not negotiate while "under fire."

"Any negotiations on the exchange of prisoners will take place after the cease-fire and the occupation’s withdrawal from Gaza," Hamas leader Musa Abu Marzouk said. "We will not negotiate under fire."

A man armed with a knife stabbed two officers working at the Mazmuria Crossing in southern Jerusalem on Thursday night, according to Israeli police.

The suspect stopped his car near the crossing's inspection station and then got out and stabbed two security personnel who were on duty, police said.

One of the victims, as well as a border police officer, "confronted the terrorist, neutralizing him with gunfire," police said.

The victims suffered "light to moderate injuries," police said.

The Palestine Red Crescent Society said it’s working to establish the first organized camp for displaced people in the city of Khan Younis in southern Gaza.

The camp would initially have 300 tents and later expand to 1,000 tents, the PRCS said.

Israeli forces have destroyed an underground tunnel near the Rantisi Hospital in northern Gaza, Israel Defense Forces spokesman Rear Adm. Daniel Hagari said at a briefing.

The tunnel infrastructure, several kilometers long, “connected different locations in the Strip,” Hagari said. “[Israeli] forces uncovered three tunnel shafts in the area of ​​the hospital, with one of them coming out of a school.”

“The tunnel network included steel doors, command control rooms, emergency rooms, many weapons that were underground and other intelligence materials,” he said.

This comes as Israeli forces “are at a very high level of readiness for the expansion of the war” in northern Gaza, Hagari said.

“We are in the final stages of the attack in the Al Burj area in the northern Gaza Strip, where we killed many terrorists,” he said.

Hagari added that Israel is also “attacking all the infrastructure that Hezbollah has built near the [Lebanon-Israel] border.”

In southern Gaza, Israeli “forces are fighting in several areas,” Hagari said. “One in the area called Al Burj in the central [Gaza] camps, where we are attacking for a third day. The second is in Khan Yunis in the south of the Gaza Strip, a major terror center of Hamas. There we expanded the operation -- today we added another division to this area and we continue to operate there with new combat methods above and below the ground.”
