It was only when the telephone rang, moments later, that he realised how close his father Dudu had come to being caught up in the bloodshed.
"He had gone into the town centre to buy some vegetables," he said. "He was so close to what happened, no more than 20 metres away, that he actually saw the explosion. He phoned straightaway to say he was all right, but the things he told me left me shaking.
"He saw bodies flying through the air and people running in all directions, scared for their lives. Then he found out there was another bomber whose belt had not gone off. If it had, he might not still be here. You see these sort of things on television, but when you are involved, it brings home the full horror.
"My dad considers himself to be lucky, because he knows it could have been so much worse."
