Why I don’t hate the person who tried to kill me in Norway’s worst terror attack from a far-right extremist. Bjorn Ihler speaks to Lives Less Ordinary, the podcast from the BBC World Service that brings you the most incredible true stories from around the world. Fifteen years ago today, on 22 July 2011, Bjorn Ihler was a 20-year-old performing arts student and a member of the youth division of the Norwegian Labour Party. He participated in the Party's summer camp on Utøya island, about 35km from Norway's capital Oslo, when Norway suffered its worst terror attack in recent history. Anders Breivik was a far-right extremist who launched a bomb attack on government offices in Oslo. Two hours later he attacked the summer camp that Bjorn was attending. 77 people were killed that day – the majority on the island. Bjorn survived and helped save two young boys who were also on Utøya. Just days after the incident Bjorn threw himself into trying to understand how someone could behave this way. Today, Bjorn is an expert in preventing radicalisation and extremism and alongside his wife co-founded the Khalifa Ihler Institute which promotes peace, human rights, and community.

Children who are so obese they’re banned from their local gyms. Two and three year olds who are so used to juice and fizzy drinks they find it difficult to drink water. This is the child obesity epidemic hitting Italy. The country is often considered the spiritual home of the fabled mediterranean diet, celebrated as the secret to a long, healthy life. But Italy’s children are now the second most overweight in the EU. The reasons for this change in a generation are complex and hotly disputed. Experts are putting it down to a daily diet heavy in pasta, pizza, potatoes, bread and meat proteins. Parents say their teenage children are eating a family dinner then going out to binge on fast food. Others accuse the parents themselves of overindulging their children from an early age. Italy is acting. It recently became one of the first countries in the world to formally recognise obesity as a chronic disease. Twenty five secondary schools in the Campania region of Southern Italy, including Naples, will take part in an ambitious clinical trial to try and get their pupils to eat more healthily in a bid to prevent a looming health crisis. Can Italy turn its child obesity crisis around? And what lessons does its experiment hold for other countries struggling with the same problem? Sofia Bettiza reports from Naples.
