At Ramlet al-Baida, on Beirut’s Corniche, a large area was cordoned off on Wednesday morning as officials inspected the scene of a deadly strike.
One military official told the BBC that personnel were dealing with unexploded ordnance.
The Lebanese health ministry said at least eight people were killed after what appeared to be a direct hit on a car. There were reports of a second attack after people gathered to help, causing further casualties.
There were no specific warnings about the strike at the seafront, where hundreds of people displaced by the conflict were sleeping in makeshift shelters.
Khoudor Housseini, whose family was staying there after fleeing the town of Chmestar in the eastern Bekaa Valley, said an Israeli drone flying overhead fired a missile at a parked car.
“After about two minutes, it targeted the car again. One missile didn’t explode,” he told the BBC. “If it had exploded, maybe we would have all died… God protected us.”
“I’m one of the people who wanted to go help, but I couldn’t. I have a little baby with me.”
Mohammed Ali, whose family was displaced from Beirut’s southern suburbs, told the BBC: “We were sleeping here peacefully and didn’t feel anything until something exploded and we woke up in a panic.”
“They said one strike had happened so we went back to sleep, thinking the targeting was over, but then the second strike happened.”
Mohammed said he grabbed two of his children and rushed them away from the area.
He complained that schools which have been transformed into displacement centres in the city were already full, leaving few options for people who have fled from their homes.
The Israel Defense Forces (IDF) has not yet commented on the strike, but it has said its military action in Lebanon is targeting Hezbollah.
