The lights on the Eiffel Tower were switched off on the evening of the attack to mourn the deaths . Nice , a city which bore witness to a similar but deadlier attack in 2016 , raised the Swedish flag at half-mast the day after the attack to show solidarity with the Swedish people . In Brussels , where a terrorist attack took place a year earlier , the ING Marnix building near the Throne metro station was also decorated with a moving Swedish flag animation
