About ten minutes later, the bomb detonated, which made debris fly almost 50 feet (15 m) away from the blast area.

[4] The head of Scotland Yard's anti terrorist squad, George Churchill-Coleman, said the 2 lb (910 g) bomb of high explosives was "clearly designed to kill."

Churchill-Coleman added that the IRA's warning was "deliberately vague" and was given too late to act upon.

[5] Prime Minister John Major said the bombing would not change British policy in Northern Ireland.

[8] The IRA maintained this pressure, bombing mainland Britain and especially the city of London as much as possible until the ceasefire of 1994.
