Irish police found a bomb on a bus near Dublin just hours before Queen Elizabeth II was due to arrive in the city. The army was called in to neutralize the device discovered in County Kildare late last night. Officials say the queen will still travel to the city today, becoming the first British monarch to visit the country since it gained independence, the Guardian reports.
The Irish have mounted an unprecedented security operation for the monarch's 4-day visit, including land, air, and sea patrols. Security forces have set up a "ring of steel" around central Dublin where the queen plans to visit sites, including the Croke Park stadium, where British troops massacred civilians in 1920. Security has been stepped up in London as well after a bomb threat from Irish militants. (More improvised explosive device stories.)
