FILE - This Saturday, Feb. 10, 1996, file photo shows the destruction of a bomb blast at South Quay in London's Docklands area in which 30 people were injured. The bomb exploded near Britain's tallest high-rise, Canary Wharf Tower, just an hour after the IRA announced Friday it was aborting a one and a half year-old cease-fire. Relations between Britain and Ireland have experienced many highs and lows in a century marked by rebellion, terror and treaties. (AP Photo/Alastair Grant, File)
