At least six people were killed, and seven were feared missing under the rubble after an Iranian ballistic missile slammed into a residential building in the central city of Bat Yam overnight Saturday.

The barrage was Iran’s second overnight attack, triggering sirens and sending residents of Tel Aviv, much of central Israel, Ashdod and parts of Jerusalem into shelters just after 2:30 a.m., with impacts later being reported in Bat Yam, Rehovot and Ramat Gan.

Six people — including an 8-year-old girl, a 10-year-old boy, and an 18-year-old boy — were killed in Bat Yam, and over 100 were wounded, rescue services said.

Seven people were considered missing, and soldiers of the IDF Home Front Command’s Search and Rescue Brigade continued to operate at the site of the impact on Sunday morning in an effort to locate and extract them, the military said.

Ribat Vaknin told Channel 12 news that her father was missing after he didn’t make it to a bomb shelter on time.

“My brother entered to take him, and then came the explosion. There was an insane shockwave. My brother was injured, my dog was injured, and they are searching for my father now,” she said.

A 50-year-old woman, identified by the initial “Gimel,” said she was searching for her dog, Joya, in the rubble of the building.

“I was at home alone. I heard the sirens and thought about going down to the bomb shelter, but first I ran to the bathroom. I heard two booms, and I thought it was over. And then, exactly as I learned that four women had been killed in the north, suddenly everything collapsed on me. The entire ceiling collapsed,” she told Ynet.

“I said to myself, that’s it, I am going to die,” she continued.

Gimel said she walked down to the shelter, which was locked, but then saw a neighbor covered in blood.

“I am thinking about my parents, who can’t get down to the bomb shelter. You feel like you are being buried alive,” she said.

Baruch, who lives on an adjacent street, told the Maariv daily, “I’ve never seen anything like this in my life.”

“I have been in wars. During the Six-Day War, I fought in the Golan Heights. But there was nothing like this. Planes flew over me. Now I feel better, I saw all the craziness and I was really scared by the power of the bomb,” he said.

Bat Yam Mayor Tzvika Brot said in a statement that “61 buildings were damaged in one way or another — six of them will need to be completely demolished.”

In Rehovot, at least 42 people were wounded, including two seriously and 13 moderately, MDA reported. One man was alive for hours under the rubble at the site of the strike, until rescuers managed to extract him.

First responders said that he was in good condition.

At the missile impact site, Golan Levy, a medic for the United Hatzalah rescue services, told the Walla news site that a one-and-a-half-year-old baby and his mother were among the injured.

“There were casualties with bleeding and fractures. Everyone was in a panic, screaming. The homes in the area — most are without bomb shelters as this is an old area — were damaged by the impact. Residents lay on the floor in front of the municipal market and waited for rescue. Some were rescued from a nearby bomb shelter,” he said.

A building belonging to the Weizmann Institute for Science in Rehovot was reportedly damaged in the barrage. According to The New York Times, which cited images shared with the newspaper, there was a fire in “at least one building containing laboratories.”

The chief of the IDF Home Front Command, Maj. Gen. Rafi Milo, said the deadly missile impact in Bat Yam “is a reminder how important it is to follow the Home Front Command guidelines.”

“Difficult days lie ahead, but we are determined. We have the spirit, the strength to act together with you to protect you and continue to save lives,” Milo added.

Four people were killed in an earlier barrage Saturday night when a missile impacted the northern Arab city of Tamra, east of Haifa.

Some 200 people overall were injured in the overnight attacks.

The IDF called on the public not to publish the locations or footage of missile impacts. “The enemy monitors the footage to improve its attack capabilities,” the military said.

The enmity between Israel and Iran escalated into unprecedented open conflict in the early hours of Friday morning when Israel launched a major offensive against Iran and its nuclear program, hitting nuclear sites, missile bases and top military officials.

Israel said it had no choice but to attack Iran, and that it had gathered intelligence showing that Tehran was approaching “the point of no return” in its pursuit of nuclear weapons.

The Israeli operation was expected to last several days at least, according to military officials, who added that the IDF was preparing for heavy fire from Iran, but asserted that “at the end of the operation, there will be no nuclear threat” from the Islamic Republic.
