Lebanon has been under Israeli bombardment and blockade since militant group Hezbollah captured two Israeli soldiers in a cross-border raid on Wednesday.
Bridges and roads around the country have been hit.
Beirut international airport has been among the targets of the Israeli bombers.
The bombardment has come from the sea as well as the air.
More than 60 Lebanese have died in the Israeli offensive. The Israelis have demanded the return of the two soldiers.
They have also demanded that Hezbollah cease rocket attacks on Israel, where children have been moved to bomb shelters.
Israelis in northern towns like Nahariyya have been under attack by dozens of Hezbollah rockets.
Several Israelis have died in the rocket attacks and a number of buildings have damaged.
In Beirut, residents have taken advantage of any break in the bombing to clean up their neighbourhoods, as here in Dahyieh - a Hezbollah stronghold.
Lebanese protesters shouted anti-Israeli slogans on the streets of Dahyieh following the attacks by Israeli forces.
With strategic roads like the Beirut-Damascus road at Sofar in the Bekaa Valley targeted in the Israeli operation, Lebanese have had to find other means of travel.
