Israel-Gaza live updates: Sirens sound in Tel Aviv as Hamas fires rocket from Gaza

A U.S. official reaffirmed Sunday that the United States was not involved in Israel's preemptive strike Saturday night on Hezbollah targets in Lebanon but had provided Israel some intelligence, surveillance and reconnaissance information believed to have been used in the mission.

The U.S. had provided some “ISR support in terms of tracking incoming Lebanese Hezbollah attacks but did not conduct any kinetic operations as they were not required," the official said.

"We continue to closely monitor the situation and remain well-postured and ready to support the defense of Israel from attacks by Iran and any of its proxies, to include Lebanese Hezbollah," the official said.

At least three people were killed overnight in the Israeli strikes on Hezbollah targets in southern Lebanon, the Lebanese Ministry of Public Health said Sunday. The casualties included two people who were killed in the village of At Tiri and one in the town of Khiam, the ministry said, adding that two additional people were injured and required hospitalization.

The Israel Defense Forces announced a new evacuation order Sunday for a small strip of land in a humanitarian area of central Gaza.

The new evacuation order for an area of Deir al-Balah came just days after the IDF ordered the evacuation of two refugee camps in the same area as the Israeli military prepared for a new ground offensive in the humanitarian zone.

The IDF suspects that Hamas terrorists are hiding in the area and using Palestinian refugees as human shields.

Sunday's evacuation order affected those living in a relatively small area of Deir al-Balah that includes five schools sheltering displaced people and tent camps around them.
The area is near the Al Aqsa Martyrs Hospital, one of the largest remaining functional hospitals in Gaza, servicing all of central Gaza.

Israel believes the Hezbollah targets in central Israel were meant to be a complex of intelligence bases and the headquarters of Mossad, the Israeli intelligence agency, just north of Tel Aviv, two Israeli security sources told ABC News.

At least three people were killed overnight in southern Lebanon, the Lebanese Ministry of Public Health said Sunday.

Two were killed in the village of At Tiri and one in the town of Khiam, the ministry said, adding that two additional people were injured and required hospitalization.

The United Nations agency in charge of peacekeeping in southern Lebanon called on Sunday for a cease-fire and for all sides to "refrain from further escalatory action."

"In light of worrying developments across the Blue Line since the early morning, UNSCOL and UNIFIL call on all to cease fire and refrain from further escalatory action," the agency said in a statement, referring to a demarcation line separating Israel from Lebanon.

There have been no reports of injuries on the Israeli side, according to emergency services in Israel.
