Mohammed Deif has been the head of Hamas' military wing.
As the Israel-Hamas war continues, efforts to secure the release of hostages taken by the terrorist organization are ongoing, and Israeli forces have launched an assault in Khan Younis in southern Gaza.
Amid ongoing Israel Defense Forces' operations in Gaza City, 50 people were killed and another 130 were injured in the last 24 hours, according to the Hamas-run Gaza Ministry of Health.
Israeli forces continue to operate in Gaza City, specifically in the Shejaiya neighborhood, the IDF confirmed in two separate releases issued Tuesday.

United Nations experts have declared that a famine has spread throughout the Gaza Strip.
Of Gaza's 36 hospitals, only 13 are "partially functioning," the UN World Health Organization spokesperson Tarik Jasarevic said Tuesday.
In northern Gaza’s Kamal Adwan hospital alone, 60 cases of severe acute malnutrition were detected last week, according to the U.N. World Health Organization.
"Fayez Ataya, who was barely six months old, died on 30 May 2024 and 13-year-old Abdulqader Al-Serhi died on 1 June 2024 at the Al-Aqsa Hospital in Deir Al-Balah. Nine-year-old Ahmad Abu Reida died on 3 June 2024 in the tent sheltering his displaced family in Al-Mawasi, Khan Younis. All three children died from malnutrition and lack of access to adequate healthcare," U.N. experts said.
"With the death of these children from starvation despite medical treatment in central Gaza, there is no doubt that famine has spread from northern Gaza into central and southern Gaza," U.N. experts said.

With CIA Director Bill Burns and White House Middle East adviser Brett McGurk working to advance a cease-fire and hostage release deal in the Middle East, two U.S. officials familiar with the negotiations said they see more flexibility from Hamas than they did previously.
The officials assessed this is coming from Hamas leader Yahya Sinwar; however, they stopped short of saying they felt a breakthrough was in the offing.
The officials also said they believe Israeli Prime Minister Benjamin Netanyahu is still committed to achieving a deal.
The American delegation headed by Burns arrived in Cairo earlier Monday to continue Gaza cease-fire talks, Egyptian state TV reported.

A new evacuation order in Gaza will "further impede delivery of very limited life-saving care," the World Health Organization said Monday.
The Israel Defense Forces issued an evacuation order in Gaza City on Monday, telling people to go to designated safe zones.
Al-Ahli and Patients' Friendly hospitals are now "out of service," with some patients referred to hospitals that are experiencing shortages of beds and medical supplies, according to WHO Director-General Tedros Adhanom Ghebreyesus. Multiple health care centers are also located within the evacuation zone, while three hospitals are close by, he said.
"These key hospitals and medical facilities could quickly become non-functional due to hostilities in their vicinity or obstruction to access," he said in a statement.
The IDF said Monday it launched a "counterterrorism operation in Gaza City targeting Hamas and Islamic Jihad infrastructure."
"Civilians were warned and a route was opened for their safe evacuation," the IDF said.
