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

Hezbollah leader Hassan Nasrallah said missile and drone strikes targeting a "base for military intelligence" near Tel Aviv, Israel, "has ended" for now.

Nasrallah said the strikes carried out Sunday constituted the first and second phases of Hezbollah's response to Israeli missile strikes in Lebanon. He said Hezbollah reserves the right to "respond" if it learns its strikes on Israel are not "sufficient."

Nasrallah said Hezbollah's missile and drone strikes targeted the Glilot military base near Tel Aviv, alleging it is a "base for military intelligence."

"It contains a large number of officers and soldiers and it manages many of the assassination operations that take place in the region, as well as the sedition and deception operations," Nasrallah alleged.

Hezbollah believes "a number of drones" reached their target. Israel Defense Forces spokesperson Rear Adm. Daniel Hagari said most of the Hezbollah missiles and drones were intercepted and denied that the Glilot military base was hit.

Hagari also confirmed that the soldier who was killed in the Hezbollah missile strike was hit by a fragment of an Iron Dome interceptor.

Nasrallah said a total of 340 missiles were fired at the Glilot military base.

A "preemptive strike" by Israel failed to cause any significant damage, according to Nasrallah.

"What happened was aggression, not a preemptive action," Nasrallah said.

Hamas leader Osama Hamdan has released a statement indicating Hamas does not accept the latest iteration of the cease-fire proposal as written.

Hamas insists that changes added by Israel since July 2 are non-starters for them, specifically, Israel Defense Forces positions in the Philadelphi corridor, an eight-and-a-half-mile long demilitarized buffer zone running along the border between Egypt and Gaza. Hamas also objected to a proposal for non-Palestinian control of the Rafah border crossing.

Hamdan said Hamas will not return to the cease-fire talks as long as the new conditions stay in the proposal.

"The occupation set new conditions for accepting the agreement and backed away from what it had previously agreed to," Hamdan said in a statement. "The delegation informed the mediators today of our opinion."

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.
