In the wake of the deadly terror attack in Barcelona, Spanish political leaders, celebrities, royals, and ordinary people have started to post images of a looped black ribbon to mourn the victims.

Many are also using the hashtag #TotSomBarcelona — we are all Barcelona.

They include Spanish Prime Minister Mariano Rajoy:

El Gobierno condena enérgicamente el atentado terrorista que ha tenido lugar esta tarde en Las Ramblas ocasionando el asesinato de varias personas y decenas de heridos. Los terroristas nunca derrotarán a un pueblo unido que ama la libertad frente a la barbarie. Toda #España está con las víctimas y sus familias. Estoy de camino a #Barcelona. La prioridad es atender a las personas afectadas y facilitar la labor de las Fuerzas y Cuerpos de Seguridad. La coordinación está siendo máxima para detener a los asesinos y reforzar la seguridad. Unidad.

Ribbons have been used as a sign of mourning and defiance in Spain since at least the 1990s, and are a familiar sight from the aftermath of attacks by Basque separatist group ETA.

Barcelona FC star Leo Messi also posted a ribbon:

Quiero mandar mis condolencias y todo mi apoyo a las familias y amigos de las víctimas del terrible atentado en nuestra amada Barcelona, además de rechazar totalmente cualquier acto de violencia. No nos vamos a rendir, somos muchos más los que queremos vivir en un mundo en paz, sin odio y donde el respeto y la tolerancia sean las bases de la convivencia.

"We won't give in, those of us who wish to live in a peaceful, hate-free world in which respect and tolerance form the basis of our coexistence are in the overwhelming majority," Messi wrote in his caption.

Following four bomb attacks on commuter trains in Madrid in 2004, which killed 191 people, people attached or painted black ribbons onto the Spanish flag, pinned black ribbons to their clothes, and hung black ribbons outside their businesses, NBC News reported at the time. People in France and Germany also wore black ribbons in solidarity.

The black ribbon has been used to signify solidarity in the face of terrorism in other countries since.

Google added a black ribbon to its search pages after an attack on Charlie Hebdo's offices in Paris claimed 12 lives in 2015. After a suicide bomber killed 22 people at an Ariana Grande concert at Manchester Arena this May, social media users fashioned a black ribbon with Grande's signature bunny ears in solidarity.

Infelizmente, as notícias não são boas. A polícia confirmou 22 mortes e mais de 50 feridos na explosão que rolou nesta segunda-feira em um show de Ariana Grande em Manchester. A CAPRICHO envia vibrações positivas para as famílias das vítimas. Força! #prayformanchester #arianagrande #manchester
