The coastal road leading from the south of Lebanon into Beirut is deserted. Many of the refugees are avoiding the road as it has been bombed.
Families from the south are sleeping in a park in central Beirut before being moved to schools in the city.
The journey from the south is very dangerous. This car had all its windows blown out by an explosion from an Israeli air strike.
Ahmed Bayashi, 33, arrived in the park last night from a village in southern Lebanon. An Israeli missile landed 100m (109 yards) from his home.
About 86,000 Lebanese refugees are staying in schools and other public buildings in Beirut.
The refugees say they want to return to their towns and villages but do not know when they will be able to.
Local organisations are providing the refugees with food and water. One man said the crisis was bringing Lebanon together.
Many of the refugees say they fled the south of Lebanon for the sake of their children.
