Crowd chants 'I'm not afraid' during tribute to Spain victims
Hundreds of people in Barcelona's main square broke into applause and chanted 'I am not afraid' after a minute's silence during a tribute to the 14 people killed and over 100 injured in two attacks. Declaring three days of mourning, Spanish Prime Minister Mariano Rajoy said, "We have received blows like this...but we also know that terrorists can be beaten."
