Humanitarian groups, saddled by years of underfunding, are struggling to keep up. They warn of a humanitarian crisis.
"The needs are escalating much faster than our capacity to respond," Mathieu Luciano, the head of the International Organization for Migration in Lebanon, said during a recent press briefing.
The government, meanwhile, is using Lebanon's largest sports stadium as a makeshift shelter, where Nazha, her husband and more than 800 other people have been sleeping in the semiopen corridors under the stands. It has toilets and sinks, but no showers and only sporadic electricity.
"It's not enough that they bring us food. ... A tin of sardines or a loaf of bread or a gallon of water, that's not enough," Nazha said Thursday from her foldout bed.
In the parking lot of the stadium where Lebanon's national soccer team regularly plays in peacetime, children played a pickup game as an Israeli drone flew overhead, recognizable by its whirring. From there, one can see and hear the bombs that have been exploding daily in nearby neighborhoods.
