"Now that the ceasefire is implemented, we should be able to deliver aid to any region," UN Humanitarian Coordinator in Lebanon David Shearer said in a statement.
Shearer said the south would remain "very dangerous" for many weeks to come and urged locals to exercise "extreme caution," due to the large quantities of unexploded artillery and mortar shells that fell across the countryside.
UN refugee agency spokeswoman Astrid van Genderen Stort said that awareness campaigns would be launched by UN agencies to inform people about the risks of handling unexploded shells.
"We cannot stop people from going home, but they have to be cautions," she told reporters.
