Tributes have poured in from across the world after the serial blasts in Sri Lanka on Easter Sunday that targeted churches and luxury hotels killed 253 and injured close to 500. And there have been multiple signs of solidarity with the island nation, from the world's tallest building being lit up in the colours of Sri Lankan flag to the lights on the Eiffel Tower being switched off. "Here’s to a world built on tolerance and coexistence," tweeted the official Twitter handle of the Burj Khalifa on Thursday. The tweet shared a photo of the building on which the flag of the country was projected. برج خليفة يضيء تضامناً مع #سريلانكا. معاً نحو عالم يسوده السلام والتسامح#BurjKhalifa lights up in solidarity with #SriLanka.

The new official figure is now 253, down from an earlier 359. The Islamic State group has claimed responsibility for the attacks. It released a video that showed eight men, all but one with their faces covered, standing under a black Islamic State flag and declaring their loyalty to its leader, Abu Bakr Al-Baghdadi. The government said there were nine suicide bombers, eight of whom had been identified.
