Israeli strikes kill 150 in Gaza as peace talks resume

Tedros Ghebreyesus, the director of the World Health Organization, said in a statement Saturday that WHO has received no updates about Dr. Hossam Abu Safiya, the director of North Gaza's Kamal Adwan hospital, since he was detained by Israeli forces on Dec. 27th.

"We continue to urge Israel to release him. We repeat: attacks on hospitals and health professionals must end. People in Gaza need access to health care. Ceasefire!" he said in a statement.

More than 150 people have been killed in Israeli attacks across the Gaza Strip over the past three days, according to Palestinian health authorities.

The series of airstrikes on dozens of Hamas targets came amid a renewed push to reach a ceasefire in the 15-month-old war and return Israeli hostages home before President-elect Donald Trump takes office later this month.

Delegations from both Israel and Hamas were dispatched to resume indirect negotiations in Doha on Friday. The talks will be brokered by Qatari and Egyptian mediators.

President Joe Biden's administration, which is helping to broker the talks, urged Hamas to agree to a deal. Hamas said it was committed to reaching an agreement deal, but it remains unclear how close the two sides are.

Approximately 77 people were killed and 145 injured over the past 24 hours in Gaza, the Hamas-run Gaza Ministry of Health said Friday.

Israeli air forces struck "approximately 40 Hamas terrorist gathering points" throughout the Gaza Strip over the past day, the Israel Defense Forces said in a release Friday.

"Prior to the strike, numerous measures were taken to mitigate the risk of harming civilians, including the use of precise munitions, aerial surveillance, and additional intelligence," the release stated.

Agnes Callamard, the secretary general of Amnesty International, said on Thursday that the organization is "extremely alarmed" by the detention of Dr. Hussam Abu Safiya -- the director of the Kamal Adwan Hospital in northern Gaza.

"He should now be considered as victim of enforced disappeared and as such at great risk of torture and ill-treatment," Callamard wrote in a post to X. Israeli authorities "must urgently disclose" his location, she added.

The Israel Defense Forces confirmed to ABC News on Thursday that Abu Safiya was in the custody of Israeli authorities and is currently being interrogated "for suspected involvement in terrorist activities and for holding a rank in the Hamas terror organization."

The IDF has alleged that Hamas and Islamic Jihad operatives were hiding inside the Kamal Adwan Hospital in Beit Lahia. Abu Safiya was initially detained on Dec. 27 during an IDF raid on the medical facility, which has been besieged multiple times by Israeli forces.
