A man who was almost killed by Anders Breivik explains how he keeps re-living it to prevent others from becoming radicalised

As Anders Breivik conducted his act of terror on the usually-picturesque Norwegian island of Utøya, methodically slaughtering 69 people and injuring dozens more at the hands of his shotgun, 20-year-old Bjørn Ihler lay low on the far southern tip of the island and somehow struck up a conversation about Christmas.

On the morning of July 22, 2011, Ihler had slept in. He only arrived to the island the night before and stayed up all night catching up with old friends.

The island played host to Norwegian Labour Party-affiliated Worker's Youth League summer camp and Ihler had travelled over from England, where he was studying theatre at Liverpool University, to "learn something about how politics was going in Norway," he told Business Insider.

That grey and rainy afternoon, he crawled out of his tent, ate some waffles for late breakfast, and trundled over to a meeting about education policy in the island's main venue.
