Israeli warplanes targeted Wednesday Haret Hreik in Beirut's southern suburbs, for the first time in nearly a week.
The strikes on southern Beirut were the first in six days, and came after caretaker Prime Minister Najib Mikati said the United States had given him assurances that Israel would curb its strikes on the capital.
The Israeli army said it struck a "strategic weapons depot" belonging to Hezbollah, under a residential building, without providing evidence.
"You are located near facilities and interests affiliated with Hezbollah, which the IDF (Israeli military) will work against in the near future", Israeli military spokesman Avichay Adraee wrote in Arabic on X.
An Associated Press photographer saw three airstrikes in the area, the first coming less than an hour after the notice.
Hezbollah has a strong presence in southern Beirut, which is also a residential and commercial area home to large numbers of civilians and people unaffiliated with the militant group.
Israel also carried out Wednesday 11 air strikes on Nabatiyeh and surrounding areas in south Lebanon, days after strikes destroyed the southern city's marketplace.
"For now, 11 strikes have mainly hit Nabatiyeh but also its surroundings," Nabatiyeh governor Howaida Turk told AFP when asked about Israeli strikes, adding that the intense raids "formed a kind of belt of fire" in the area. She reported casualties but could not provide a precise toll.
