PARIS (AP) — The dead and injured in Barcelona were a snapshot of the world — men, women and children from at least two dozen nations — testifying to the huge global appeal of the sun-kissed city with its bounty of must-visit sites and star-studded football team. Families, friends and government officials from Paris to Sydney, San Francisco to Berlin scrambled Friday to discover whether their loved ones and citizens were among those mowed down by suspected Islamic extremists who zig-zagged down Barcelona's always crowded Las Ramblas promenade in a white van, killing and maiming indiscriminately.
