Fries are a symbol of Belgium — if a bit of a cliché — but this image quickly gained traction on Twitter after Tuesday's terror attacks which killed at least 31 people in separate attacks at the airport and metro in Brussels.

The image wasn't created specifically in response to the attacks but was adapted from an old Burger King ad.

The image dates back to 2008, when it was used for a campaign in connection with the launch of a restaurant near Auckland in New Zealand. 

On social media, the image was cropped to remove the text. It is not clear who first repurposed the ad.

Cartoons of a crying Tintin are also being used to show support for Belgium.
