The explosions could be heard across Beirut, an earth-shattering thunder that rolled across the city on Friday evening. For Doctor Jihad Saadeh, director of Lebanon’s largest public hospital, it was the beginning of a sleepless night of carnage.

Saadeh’s private clinic was just a few hundred meters from the target of Israeli warplanes, which dropped bombs on at least six residential buildings that collapsed before his eyes. Their aim was to kill Hassan Nasrallah, the leader of Hezbollah, whose death was confirmed on Saturday.

“We saw the red jets of smoke shooting into the sky, the buildings just collapsing,” he said. He had run from his clinic to Rafik Hariri Hospital to prepare his staff.

“At first we only got bodies,” he said. “The buildings just collapsed. Everyone was under the rubble. There were no injuries, only deaths.”

The bombing caused devastating damage across Lebanon, from the southern suburbs of Beirut to the Bekaa Valley in the east and throughout the south. Israeli warplanes bombed areas far from Hezbollah’s traditional bases, including Mount Lebanon and Chouf.

According to Lebanese state news, huge clouds of orange and red smoke rose between Beirut’s tightly packed apartment buildings as the sound of sirens filled the city, which suffered at least 11 airstrikes on Friday evening and Saturday morning.

Several residential buildings were leveled in the attacks that killed Nasrallah. As the sun rose, a huge crater left by the bombs in Dahiyeh could be seen from the hills surrounding Beirut.

Lebanon’s Health Ministry asked hospitals near Beirut that were not affected to stop accepting non-urgent cases to make room for patients evacuated from hospitals in the capital’s southern suburbs.

At least eleven people were killed and 108 injured in the bombings, the Health Ministry said on Saturday. This is likely an undercount as it only includes hospitals that reported their data to the ministry.

There was a tense period of mourning in Beirut, hours after Hezbollah confirmed Nasrallah’s killing on Saturday. Shops closed across the city.

Israel, meanwhile, continued its assault against Hezbollah, saying it killed another of the group’s commanders on Saturday in an attack on Dahiyeh, the southern suburb where Nasrallah was assassinated. As its drones continually buzzed over Beirut, the Israeli military vowed to continue its attacks.

Many families who had fled their homes were dazed and frightened and struggling to come to terms with what had happened.

After Nasrallah’s killing on Friday evening, the Israeli military warned residents of Beirut’s southern suburbs to evacuate for “your safety and the safety of your loved ones” as it prepared to intensify its bombing campaign.

Those on the social media platform It called on residents living there and in surrounding buildings to leave the Israeli military immediately, as the Israeli military would be “forced to act against these (Hezbollah) interests in the immediate future.”

Residents of the Burj al-Barajneh Palestinian refugee camp in Beirut’s southern suburbs said panic spread quickly through the narrow streets and concentrated buildings as Israel warned that surrounding neighborhoods would be bombed.

A woman from the camp, a Palestinian refugee who fled Syria for Lebanon in 2012, had to run again on Friday evening, this time to a seaside walkway.

“We fled from the terror. As soon as we heard the evacuation orders, we left,” she said. Her family stood on the side of a dark highway as the sound of airstrikes echoed around them before a van finally offered them a ride.

“We definitely won’t be returning. They’re still bombing,” she said.

All around them were families who had made the same journey. As the sun rose higher along the Beirut Corniche where the refugee wasS After seeking refuge, exhausted fathers hung blankets between palm trees to provide shade for their families.

Plastic bottles and bags of potato chips littered the sidewalk, usually crowded with joggers and table tennis players. Instead, children and grandparents sat on the floor, eating bread and drinking tea passed out by volunteers.

Fatima, an 18-year-old girl who asked that her real name not be used, had fled the suburb of Lailaki with her family after midnight. When the bombings began on Friday evening, they initially decided to stay in their house.

But the explosions were so intense, so loud and so close that she lost consciousness.

“I fainted,” she said. “Our house became like paper,” she added, moving her hand to show how her home seemed to fold and shake.

The family only decided to leave after the Israeli military issued an evacuation order for homes in their neighborhood

Surrounded by her suitcases on the seafront, Zaynab, Fatima’s aunt, said she didn’t know where she would go next or whether she would be able to return to her home.

“We don’t even know if our house is still there to return to,” Zaynab said.
