A bomb left along the route of a Martin Luther King Jr. Day parade was sophisticated, with a remote detonator and the ability to cause many casualties, an official familiar with the case said Wednesday.

"They haven't seen anything like this in this country," the official said. "This was the worst device, and most intentional device, I've ever seen"/Nicholas K. Geranios, AP. More here.
