Israel said that it struck three terror cells in southern Lebanon on Saturday. The IDF also said it carried out strikes against Hezbollah infrastructure and shelled areas in southern Lebanon.

The strikes came amid Hezbollah rocket, missile and drone attacks on northern Israel on Saturday, according to the IDF. According to Israel, 80% of the launches fired by Hezbollah toward Israel fell in Lebanon.

The IDF said it has located and destroyed a hideout apartment of Yahya Sinwar -- a Hamas leader -- near Gaza City in the northern Gaza Strip.

IDF soldiers examined the apartment using additional technological means and found that a strategic tunnel shaft was located on the basement floor. The soldiers inspected the tunnel shaft and reached a 715-foot tunnel with a depth of over 65 feet that was apparently used by the senior officials of Hamas’ Military and Political Wing, according to the IDF.

The IDF said that the tunnel had an electrical network, ventilation and sewage infrastructure, hideout materials, prayer rooms and resting rooms. The IDF said the tunnel was built so that it would be possible to stay inside it and conduct combat for long periods of time.

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."

Gadi Hagi, a 73-year-old American-Israeli hostage and member of Kibbutz Nir Oz, has been confirmed dead, the kibbutz said.

Hagi was killed on Oct. 7 at the kibbutz and his body was taken to Gaza where it's still being held, according to a kibbutz spokesperson.

Hagi’s wife, 70-year-old Judy Weinstein, is wounded and still being held hostage, the kibbutz said.

Hagi and his wife were shot and kidnapped on Oct. 7, according to the Hostage Center.

"Gadi was a man full of humor who knew how to make those around him laugh," the Hostage Center said in a statement. "A musician at heart, a gifted flautist, he played in the IDF Orchestra and was involved with music his whole life."

Hagi was a father of four and a grandfather of seven.

Hagi reportedly has ties to New York.

"May Gadi's memory be a blessing," New York Gov. Kathy Hochul wrote on social media. "There are still many hostages -- including many with New York connections -- being held in Hamas captivity."

President Joe Biden said he was "heartbroken by the news."

"We continue to pray for the well-being and safe return of his wife, Judy," Biden said in a statement. "We are praying for their four children, seven grandchildren, and other loved ones and are grieving this tragic news with them."

Biden said Hagi's daughter joined, via phone, his meeting last week with families of hostages.

"Those families bravely shared with me the harrowing ordeal that they have endured over the past months as they await news of their loved ones," Biden said. "I reaffirm the pledge we have made to all the families of those still held hostage: we will not stop working to bring them home."
