Middle East live updates: Israel threatens Houthis with 'miserable fate'

A missile launched from Yemen was intercepted by Israeli air forces, the Israel Defense Forces said in a Monday night statement, amid continued Israeli and Houthi long-range attacks.

Sirens sounded "due to the possibility of falling shrapnel from the interception," the IDF said.

The latest missile launch came shortly after Danny Danon -- Israel's ambassador to the United Nations -- said Israelis "have had enough" of attacks from the Houthis in Yemen, ongoing since October 2023 in protest of Israel's war in Gaza.

"Israel will not stand by waiting for the world to act," Danon said.

Addressing the Houthi leadership, he added, "Let me remind you what happened to Hamas, to Hezbollah, to [former Syrian President Bashar] Assad and to all those who thought to destroy us."

"This is not a threat, it is a promise," Danon said. "You will share the same miserable fate."

Ukrainian Foreign Minister Andrii Sybiha on Monday met with Syria's de facto leader Ahmed al-Sharaa -- also known by nom de guerre Abu Mohammad al-Jolani.

Sybiha became the latest foreign representative to meet with Sharaa in Damascus, where the latter's Hayat Tahrir al-Sham forces and their allies are establishing a transitional government having toppled former President Bashar Assad.

Sybiha wrote on X that he "personally conveyed the message" of Ukrainian President Volodymyr Zelenskyy. "We are with you and ready to assist in restoring normal life, stability and food security," Sybiha said.

"We rely on the new Syria respecting international law, including Ukraine's sovereignty and territorial integrity," he added. "This will pave the way to fully restoring our diplomatic ties, political dialogue and diplomatic presence. We are ready to develop cooperation in a number of areas."

The visit came days after Zelenskyy announced Kyiv's dispatch of 500 tons of wheat flour to Syria as part of the "Grain from Ukraine" humanitarian program in cooperation with the World Food Program.

World Health Organization Director-General Tedros Adhanom Ghebreyesus said early Monday that Gaza's beleaguered hospitals "have once again become battlegrounds and the health system is under severe threat."

Ghebreyesus said the Kamal Adwan Hospital in the north Gaza town of Beit Lahia "is out of service," following an Israeli raid which itself came after several weeks of encirclement and bombardment.

Israeli forces raided the compound on Friday, forcibly evacuating all remaining patients and staff. The Israel Defense Forces said it detained 240 alleged militants, among them hospital director Dr. Hossam Abu Safiya. The IDF said the hospital was a "command center" for Hamas "military operations" in the surrounding area.

Ghebreyesus said Safiya's "whereabouts are unknown. We call for his immediate release."

Kamal Adwan patients were transferred to the Al-Shifa Hospital in Gaza City and the Indonesian Hospital in Beit Lahia, both of which have also reported repeated Israeli attacks. The latter "is itself out of function," Ghebreyesus said.

"Seven patients along with 15 caregivers and health workers remain at the severely damaged Indonesian Hospital, which has no ability to provide care," he added.

Four patients were detained by the IDF during their transfer out of Kamal Adwan Hospital, the WHO chief said.

Two other facilities -- the Al-Ahli Hospital and Al-Wafa Rehabilitation Hospital in Gaza City -- were also attacked and sustained damage on Monday, Ghebreyesus said.

"We repeat: stop attacks on hospitals," he wrote. "People in Gaza need access to health care. Humanitarians need access to provide health aid. Ceasefire!"

The family of Dr. Hussam Abu Safiya, the director of Kamal Adwan Hospital in the Gaza Strip, is pleading with the international community to help learn his whereabouts, alleging he was detained by Israeli forces during a recent raid on the medical facility.

The family posted a message on Abu Safiya's official Instagram page, on which the doctor had been posting updates about the hospital's functioning, pleading, "We do not know the fate of our father."

"We appeal to every compassionate individual and all international organizations and institutions to take action," said the family, asking the international community to apply media pressure and make appeals to "help us push for his swift release from captivity."

The message said Abu Safiya is still recovering from injuries he suffered a month ago while working at the hospital.

The Israel Defense Forces said in a statement released on Saturday that Abu Safiya is suspected of being a Hamas terrorist and is being held in Gaza.

Abu Safiya had not been arrested in previous IDF raids of the hospital.
