A group of men arrested in Denmark on Wednesday were about to mount a ''Mumbai style'' attack on the Danish newspaper that ignited Muslim fury around the world by publishing satirical cartoons of the Prophet Muhammad in 2005, the head of the Danish Security and Intelligence Service said. Several European countries have been on high alert for months over the possibility of an attack modeled on the 2008 assault on Mumbai, India, in which 10 highly trained and heavily armed men stormed hotels, train stations, restaurants, a Jewish center and other sites, in a bloodbath that left 163 dead.
