As Barcelona officials assured the public that the city’s subway system is safe, the 14 recently arrested suspects are believed to have had plans to hit public transportation targets in several European cities. Authorities believe three of those arrested were prepared to carry out suicide bombings. Spanish police believe that three suspects remain on the loose, and may be trying to travel to Germany and France to stage attacks there. Of the 14 originally arrested, ten remain and jail, and four have been released.
