Israel-Gaza updates: Israel says it agrees to cease-fire, hostage release

Israeli troops have turned Nasser Hospital, the main medical center serving the southern Gaza Strip, into a "military barracks" and are "endangering the lives of patients and medical staff," according to Gaza's Hamas-run Ministry of Health.

The health ministry said Monday that patients and medical staff inside Nasser Hospital are now without electricity, water, food, oxygen and treatment capabilities for difficult cases since Israeli ground troops raided the facility in the southern Gaza city of Khan Younis last week.

The World Health Organization, which warned on Sunday that Nasser Hospital "is not functional anymore," said more than 180 patients and 15 doctors and nurses remain inside the hospital.

The WHO said it has evacuated 14 critical patients from the hospital to receive treatment elsewhere.

The Israel Defense Forces alleges that Hamas, the Palestinian militant group that governs Gaza, has been conducting military operations out of Nasser Hospital and other medical centers in the war-torn enclave -- claims which Hamas denies.

The Israel Defense Forces said its fighter jets hit two Hezbollah weapons storage facilities in Lebanon on Monday.

The IDF said this was in response to the unmanned aerial vehicle launched toward northern Israel earlier in the day, and the Israelis believe it was most likely launched from Lebanon by Hezbollah.

The IDF also said its fighter jets have struck some Hezbollah terrorist infrastructure in Lebanon on Monday.

The Israel Defense Forces said Monday that it has arrested 200 suspects at Nasser Hospital in the city of Khan Younis in the southern Gaza Strip.

Gaza's Hamas-run Ministry of Health said Monday that the IDF arrested medical staff at Nasser Hospital, including the director and the only doctor responsible for caring for patients in the intensive care unit.

Israeli ground forces stormed the hospital last week, looking for members of Hamas who the IDF alleges have been conducting military operations there. Hamas, the Palestinian militant group that governs Gaza, has denied the allegations.

Nasser Hospital is the main medical center serving southern Gaza and was -- until now -- the only fully functioning hospital in the war-torn enclave. The World Health Organization said Sunday that Nasser Hospital "is not functional anymore" after Israeli troops raided the facility.

The Israel Defense Forces said Monday morning that its ground troops and special forces are "continuing to operate" in the western part of Khan Younis, a city in the southern Gaza Strip.

The IDF said its ground troops conducted "targeted raids on terror targets" in western Khan Younis over the past day, "during which AK-47s, drones, an RPG, explosive devices, and additional military equipment were located." The soldiers on the ground also coordinated with the Israel Air Force's fighter jets overhead to kill "terrorists who were operating adjacent to the troops in the area," according to the IDF.

"During additional activity in western Khan Yunis, IDF ground troops used a drone to identify a terrorist cell that was approaching the troops," the IDF said in a statement. "In response, the troops directed an aircraft to eliminate them. A short while after, four additional terrorists were identified in the area, who were also eliminated by an IAF aircraft."

Meanwhile, the IDF said its special forces "encountered armed terrorists, conducted targeted raids on terror targets, seized weapons and directed a helicopter to strike and eliminate an additional terrorist."
