This Easter Sunday will be recorded as the gloomiest day in the history of Sri Lanka with serial blasts claiming at least 138 lives and injuring more than 400 people.

The deadly explosions rocked at least three luxury hotels and a church each in Colombo, in Katana, some 50 km north of the capital, and in the eastern province of Batticaloa around 8.45 am when hundreds had gathered to celebrate Easter.

The entire world is condemning the blasts, and the sporting fraternity is equally shocked. Taking to Twitter, Indian cricket team captain Virat Kohli posted: ”Shocked to hear the news coming in from Sri Lanka. My thoughts and prayers go out to everyone affected by this tragedy. #PrayForSriLanka.”

Tennis star Sania Mirza tweeted, ”What is happening to this world. May God help us all .. really .. #SriLanka.”

Many other sporting legends, such as India cricket team vice-captain Rohit Sharma, veteran cricketer VVS Laxman, too posted such messages on Twitter.

The Christian community in Sri Lanka was celebrating the Easter Sunday, an important festival marking the resurrection of Jesus Christ, when the blast occurred.

Christians form around 7 per cent of the Sri Lankan population, with Buddhists accounting for around 70 per cent, followed by Hindus and Muslims.
