No matter how inured to violence Northern Ireland had become by 1998, most people here remember where they were and what they were doing when they heard about the Omagh bomb. It was such a shocking aberration because of the high death toll, the cross-community impact and the timing. Twenty-nine people were killed by a republican dissident group, four months after peace had been declared with the signing of the Good Friday Agreement. The victims were men, women and children, locals and foreigners, Protestants and Catholics, and neither. Inaccurate telephone warnings meant the police shepherded people towards the car bomb rather than away from it. • Subscribe to ITV News on YouTube: http://bit.ly/2lOHmNj • Get breaking news and more stories at http://www.itv.com/news Follow ITV News on Facebook: https://www.facebook.com/itvnews/ Follow ITV News on Twitter: https://twitter.com/itvnews Follow ITV News on Instagram: https://www.instagram.com/itvnews/
