The US Presidential Cadillac, nicknamed "The Beast", is seen stuck on a ramp at the American Embassy in Dublin in this still image taken from video. Specially built to withstand bombs, bullets and chemical attack, the car beached itself on the top of the ramp as it tried to exit the embassy during Obama's one-day visit to Ireland. The White House later said Obama and his wife, Michelle, were not in the vehicle at the time.
