Hamas confirmed the death of its leader, Yahya Sinwar, in a video statement by senior official Khalil Al Hayya, who has served as chief negotiator for the militant group in talks over a possible agreement on a ceasefire and the release of hostages in Gaza .

In a televised address, Al Hayya said Hamas will not release Israeli hostages until “the aggression against our people in Gaza stops,” Israel fully withdraws from the enclave and Palestinian prisoners in Israel are released.

Here’s what else you need to know:

More details emerge: The chief pathologist who performed an autopsy on Sinwar’s body told CNN that the Hamas leader was killed by a gunshot wound to the head. The Israeli army had previously said nothing about the firing of a deadly gunshot by its troops. Asked for comment, an IDF spokesperson told CNN that a firefight took place and that the battle ended when Israel fired a tank shell at the building. The IDF is still trying to determine all the details, the spokesperson added. The pathologist further told CNN that when Israeli forces found a body similar to Sinwar’s on Wednesday, his finger was cut off and sent for DNA testing to identify him.

US response so far: US President Joe Biden said ending the conflict in the Middle East after Sinwar’s death will still be difficult. US Defense Secretary Lloyd Austin said the US could “very possibly” play a role in the stabilization efforts in Gaza after the war with Israel ends, adding that this would have to be done jointly with allies in the region defined.

Blockade of medical organizations: The World Health Organization has accused Israel of barring multiple medical organizations from entering Gaza – marking the first time entire health agencies have been barred from the enclave during the more than year-long war. Specialists who were denied entry had to support ‘already overburdened’ staff in carrying out medical treatments, including surgeries, in pressurized facilities such as the Nasser Medical Complex and the European Hospital in southern Gaza and Al-Aqsa Hospital in central Gaza, WHO said. COGAT, the Israeli agency that coordinates the inspection and delivery of humanitarian aid to Gaza, has denied the allegations.

Gaza’s strained healthcare system: Kamal Adwan Hospital, one of the few functioning hospitals in northern Gaza, is overwhelmed by the volume of incoming patients, with tired staff and without medical supplies and food, its director said. “This is a catastrophic situation in every sense of the word,” Dr. Hussam Abu Safiya to CNN in a video message. “From yesterday until now, no one has slept.” In addition, the hospital is struggling with the number of premature babies due to the stress on pregnant women during the heavy bombardments in northern Gaza, he added.

Israel continues its operations in Lebanon: Israel has issued an evacuation notice to residents of 23 villages in southern Lebanon, urging them to move north. Some of the villages mentioned in Friday’s announcement had been mentioned in previous alerts. On Tuesday, the Middle East director of the United Nations Refugee Agency (UNHCR) said that about a fifth of Lebanon’s population has fled their homes, and about a quarter of the country is under Israeli military evacuation orders. Israel also called up “an additional reserve brigade for operational missions” in northern Israel against Hezbollah, the IDF said.
