The fire in the customs area of the port of Beirut has now been contained and there is no risk of it spreading, the head of the Lebanese civil defence, Raymond Khattar, told the NNA broadcaster.
According to Khattar, fire brigades and civil defence teams have circled the flames.
Earlier in the day, a fire erupted at a warehouse storing tyres and oil at the Beirut port.
The warehouse is located in the duty-free zone of the port. The cause of the blaze is still unknown, a military source told Reuters.
The Lebanese army said they would be using helicopters to extinguish the fire. They also warned that the use of drones was prohibited in the port area since aviation was involved in putting out the fire.
According to the country's Red Cross chief, there is no danger of any explosion resulting from the port's fire, and nobody has been killed or seriously injured, although some cases of people facing shortness of breath have been reported.
Local residents took to Twitter to say how frightened they were to see the fire, remembering the tragedy that happened last month.
On 4 August, the port of Beirut was hit by a huge explosion, which the authorities blamed on the improper storage of 2,750 tonnes of ammonium nitrate. The blast caused an estimated $15 billion in damages and prompted the country's government to resign.
