Cities around the world have lit up their landmarks in the colours of the Union Flag, in solidarity with London following the terrorist attack.
The Brandenburg gate in Berlin is the latest landmark to be lit up with the Union Flag.
On Thursday afternoon the gate was illuminated and the spectacular image was broadcast around the world.

On Wednesday evening Tel Aviv turned their city hall red, white and blue on one side, with the Israeli flag on the other.
Later in the evening in Paris, the Eiffel Tower was to have its lights switched off, in mourning, to show Paris's support for London.
Anne Hidalgo, mayor of Paris, whose city has suffered deadly extremist attacks in recent years, announced that the tower would turn off its twinkling lights at midnight.
Three French teenagers on a school trip were among those injured in Wednesday's attack targeting pedestrians on London's Westminster Bridge and a police officer on the nearby Parliament grounds.
French President Francois Hollande offered support for Britain and the investigation.
And in Birmingham, the leader of the city council announced that their library was being lit up.
"The @LibraryofBham lit to show Birmingham's solidarity with London. Our thoughts are with everyone affected by today's #Westminster attack," tweeted John Clancy.
