The United States Agency for International Development (USAID) says up to 2.5 million people in Lebanon need immediate humanitarian food assistance.
In a report published on Thursday, USAID stated that the number of those in need of assistance has increased dramatically.
Several regions are expected to remain at crisis level until January, including the capital Beirut and its southern suburbs.
According to the report, current and expected disruptions in the food supply chain are forcing households to stockpile food and basic necessities amid rising prices for bread and other staples.
Israel attacked Lebanon with a series of airstrikes, killing more than 1,500 people and injuring more than 8,000.
A quarter of Lebanon’s territory is under Israeli military displacement orders, a sign of the growing scale of the humanitarian crisis.
