Israel-Gaza live updates: Blinken, Abbas meet on restoring 'calm' in West Bank

Doctors Without Borders called for a ceasefire Saturday saying the conflict has reached "a new low in an endless stream of unconscionable violence." The organization, which has been providing medical care to people in Gaza, also condemned world leaders for not calling for a ceasefire.

"The deadly attack outside the gate of Al-Shifa hospital impacting an ambulance is horrendous. This is a lethal attack outside Gaza's main and busiest hospital, where our staff work daily to provide lifesaving medical care. We have repeatedly called for an immediate and total ceasefire, for the protection of healthcare facilities, as well as medics, patients and people who are taking shelter there," Doctors Without Borders said in a statement Saturday.

"This is a new low in an endless stream of unconscionable violence. The repeated strikes on hospitals, ambulances, densely populated areas and refugee camps are disgraceful. How many people have to die before world leaders wake up and call for a ceasefire?" Doctors Without Borders said.

This comes as the Palestinian death toll rises to 9,488 -- including 3,900 children and 3,509 women -- and 24,158 Palestinians were injured, according to the Hamas-run Gaza Health Ministry.

One physician described seeing an ambulance hit outside Al-Shifa hospital.

"We were standing inside the hospital gate when the ambulance was directly hit in front of us. There were bloody bodies everywhere. Many were killed immediately, while we rushed others to the operating room for emergency care," Dr. Obaid, a Doctors Without Borders doctor at Al Shifa hospital, said.

The Israel Defense Forces claimed its aircraft hit an ambulance that it believes was being used by Hamas and called for civilians to move south for safety.

Turkey announced it is recalling its ambassador to Israel due to the "humanitarian tragedy in Gaza caused by the continuing attacks by Israel against civilians," the country's Ministry of Foreign Affairs said Saturday.

"In view of the unfolding humanitarian tragedy in Gaza caused by the continuing attacks by Israel against civilians, and Israel’s refusal of calls for ceasefire and continuous and unhindered flow of humanitarian aid, it was decided to recall our Ambassador in Tel Aviv, H.E. Mr. Şakir Özkan Torunlar, to Ankara for consultations," according to a statement.

U.S. Secretary of State Antony Blinken has now added a stop in Ankara, Turkey, during his diplomatic mission to the region.

U.S. Secretary of State Antony Blinken is set to meet with Jordan’s King Abdullah on Saturday and will join a meeting of foreign ministers of five Arab countries, also attended by a representative of the Palestinian Authority led by Mahmoud Abbas.

The prime objective of the talks is to ease Gaza’s growing humanitarian crisis, but that mission is complicated by Israel's insistence there can be no temporary cease-fire until all hostages held by Hamas are released. Israel has also presented the argument that a cease-fire would be in Hamas’s favor.

Meanwhile, U.N. Secretary-General Antonio Guterres has again called for an immediate cease-fire to allow humanitarian aid into the Gaza Strip, saying the conditions in Gaza are now "horrific" with food and water needed along with fuel for generators that power hospitals.

The U.N.’s director for Palestinian refugees says that the average Gaza inhabitant is living on two pieces of bread made from flour the UN had stockpiled and that people in southern Gaza have been forced to do all their washing on the beach using seawater as clean water runs out.

Thirteen people were killed and 26 were injured from a blast that struck ambulances at the gate of Gaza's Al-Shifa hospital complex, according to the Hamas-run Gaza Health Ministry.

The Palestinian Red Crescent Society said the group of ambulances were returning to the hospital from a mission to transport injured people to the Gaza-Egypt Rafah border crossing.

The Israel Defense Forces said its aircraft hit an ambulance that it believes was being used by Hamas.

"We have information which demonstrates that Hamas' method of operation is to transfer terror operatives and weapons in ambulances," the IDF said.

"A number" of Hamas terrorists were killed in the blast, the IDF said.

The IDF said, "We emphasize that this area is a battle zone. Civilians in the area are repeatedly called upon to evacuate southwards for their own safety."
