Bike enthusiast undeterred in Tajikistan after IS attack

En route to mountainous Tajikistan's "roof of the world" lies a hastily-erected memorial to four bike tourists killed in an attack claimed by the Islamic State group late last month. But biking enthusiast Pau Ros won't be deterred from his trip over the legendary Pamir Highway: "We are not going to change our lives because that is what these bad people want," he says.
