Crowd Falls to Ground

The attack came about three hours after the winners had crossed the finish line. A loud explosion on the north side of the street went off first, followed by a second blast a few seconds later.

A number of people were bloodied. Dr. Albert Pendleton, who was stationed five feet from the finish line, described to the PBS NewsHour what he encountered: "almost all of (the injured had) lower extremity injuries. I think the blast just basically ... blew out the legs of everybody."
