German Chancellor Angela Merkel has asked the government to spend €500 million to fight the Berlin blaze.
She has also ordered an investigation into the causes of the fire.
The fire is burning in the city centre, which has seen a surge in violence over the past month.
But what does the fire actually look like?

The agency said more than 300 people had been injured.
The German capital was forced to close all schools on Saturday due to the fire, as well as a number of other buildings.
“The fire has spread to several buildings, and we will have to work with all the departments to contain the fire,” said Interior Minister Thomas de Maiziere.
The Berlin fire is a reminder of how fragile the German city remains, despite a strong recovery in recent months.
There are no major cities with more than 10,000 residents left in the capital.
About 2,000 firefighters were battling the fire in the district of Kreuzberg, which includes the offices of the federal parliament and the German ambassador to the United States.
There were no reports of injuries or deaths.
“We have a huge loss of life, but we will be able to recover, and this will be good for Germany,” De Maizier said.
The city has a population of 1.1 million, but it has lost around 1,500 residents since July.
Many of those were German citizens, and their homes were also damaged.
