Chilling CCTV footage has emerged showing a suicide bomber calmly patting a child on the head and shoulder moments before he walked into a packed Sri Lankan church, unleashing carnage. The images capture the final seconds of serenity before the calm was shattered with a series of coordinated attacks that would between them claim more than 350 lives at six sites across Sri Lanka. Security camera footage from outside St Sebastian’s Church in Negombo shows a bearded man in a light blue shirt, navy trousers and sandals appear on a pathway and cross a courtyard outside the church.
