Cities across the world used their landmarks to pay respect to those killed in a deadly van attack in one of Barcelona’s busiest districts on Thursday.

In some cases, global landmarks were lit up in red and yellow, the colours of the Spanish flag. Others, such as the Eiffel Tower, went completely dark.

At least 13 people were killed and 80 wounded after a white van leapt onto a sidewalk and plowed into pedestrians in Las Ramblas, one of the city’s top tourist destinations. The Islamic State group has claimed responsibility for the attack.

The victims were honoured in public displays across the globe, from New York City to Tel Aviv to Toronto.

In Nice, France, which lost 86 people in a truck attack on Bastille Day in 2016, the mayor announced that flags would be lowered to recognize those killed in in Barcelona. A special homage will be held on Friday.

New York City illuminated its One World Trade Center, a towering symbol in resilience over terror, in red and yellow.
