Israeli forces issued an evacuation order in the vicinity of the Al Aqsa Hospital, Deir Al Balah, in central Gaza, urging people to flee, according to a statement from Doctors Without Borders Sunday.

"An explosion approximately 250 meters away triggered panic with many choosing to leave the hospital," the organization said.

Of the approximately 650 patients in the hospital prior to the explosion, only 100 remain, with seven in the intensive care unit, according to the Palestinian Ministry of Health.

Doctors Without Borders is considering suspending wound care for the time being, while trying to maintain lifesaving treatment, according to the statement.

"This situation is unacceptable," the organization said. "Al Aqsa has been operating well beyond capacity for weeks due to the lack of alternatives for patients. All warring parties must respect the hospital, as well as patients' access to medical care."

Sirens sounded in Tel Aviv Sunday night for the first time since January as Hamas launched a single rocket toward central Israel.

The Israel Defense Forces said the Hamas rocket fell into an "open area" in Rishon LeTsiyon, south of Tel Aviv.

Israeli emergency services officials said no one was injured by the rocket, but a 26-year-old woman was hurt going to a shelter.

Hamas confirmed it fired an "M90" rocket at Tel Aviv.

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."
