Israel-Gaza-Lebanon live updates: Israel kills 5 in central Beirut, officials say

The U.S. is rolling out sanctions against six senior Hamas leaders accused of facilitating the transfer of weapons and funds into Gaza to support the group’s terror activities as well as smuggling in construction materials to build the underground tunnels critical to its operations, according to the Biden administration.

“There is no distinction between Hamas’ so-called military wing and its political leadership,” State Department spokesperson Matthew Miller said in a statement announcing the tranche of sanctions.

Three of the targeted individuals are based in Turkey, according to the U.S. Treasury Department.

Despite the denials coming from Hamas and the Turkish government, two U.S. officials say that the bulk of Hamas’ political wing has now relocated to Turkey following the group’s ouster from Qatar.

The U.S. has turned a blind eye to Hamas’ relationship with NATO ally Turkey for years, which allows the U.S. designated terror group to openly recruit, fundraise and interface with its government officials.

Turkish President Recep Tayyip Erdogan has said he hopes to strengthen ties with the U.S. when President-elect Donald Trump takes office. However, Trump’s cabinet is expected to feature many staunchly pro-Israel voices who will object to Turkey’s tolerance of Hamas -- potentially complicating Erdogan’s plans.

Kamal Adwan Hospital is running out of medical supplies, and more people with cases of malnutrition are arriving at the hospital because of the lack of food and water allowed into northern Gaza, the hospital director said in comments Tuesday.

"⁠There are a number of cases of malnutrition that have begun to arrive, including children and the elderly," Dr. Hussam Abu Safia, the director of Kamal Adwan hospital said.

"The health system is working under extremely harsh conditions to the point that we have started losing numbers of infected people due to the lack of medical supplies," Abu Safia added.

At least 50 people were killed, and 110 people were injured in Gaza over the past 24 hours, the Hamas-run Gaza Ministry of Health said.

The International Committee of the Red Cross and the Palestine Red Crescent Society transferred 15 patients from Al Awda Hospital in north Gaza to Al Shifa Medical Complex in Gaza City Sunday, the ICRC said in a statement Tuesday. The patient transfers were requested by the hospitals, the ICRC said.

The organizations also delivered medical supplies to three hospitals in Gaza City Monday, the ICRC said in a post on X.

"The delivery and medical transfer came in the wake of another large-scale attack in the Beit Lahia area of ​​the Northern Governorate, in which dozens of people were killed and many more injured," the ICRC said.

In a third incident, a UNIFIL patrol was "passing through" a village, and "an armed person directly fired at the patrol," UNIFIL said. No injuries were reported from this incident.

UNIFIL is investigating the incidents and has informed the Lebanese armed forces about them, UNIFIL said.

Berri said the U.S. is managing guarantees about Israel's position on the proposal, according to Lebanese state media.
