of the Royal Green Jackets were on the stand performing music from Oliver! to a crowd of 120 people. It was the first in a series of advertised lunchtime concerts there. Six of the bandsmen were killed outright and the rest were wounded; a seventh died of his wounds on 1 August. At least eight civilians were also injured. The bomb had been hidden under the stand some time before and triggered by a timer. Unlike the Hyde Park bomb, it contained no nails and seemed to be designed to cause minimal harm to bystanders. Aftermath At least 51 people were injured, and a total of 22 people were admitted to hospital as a result of the blasts: 18 soldiers, a police officer, and three civilians. The IRA claimed responsibility for the attacks by deliberately mirroring Prime Minister Margaret Thatcher's words a few months before when Britain entered the Falklands War, proclaiming that "the Irish people have sovereign and national rights which no task or occupational force can put down". Reacting to the bombing, Thatcher stated: "These callous and cowardly crimes have been committed by evil, brutal men who know nothing of democracy. We shall not rest until they are brought to justice." The bombings weakened public support in the United States for the Irish republican cause. The CIA and the FBI ramped up their anti-IRA activity, and public opinion polls showed that sympathy for the IRA in particular, and Irish re-unification in general, plummeted in the United States in response to the attacks. Charles Haughey, Taoiseach of Ireland, said: "Those responsible for these inhuman crimes do irreparable damage to the good name of Ireland and the cause of Irish unity." Sefton, a horse that survived the attack at Hyde Park despite suffering serious wounds, became famous after appearing in many television shows and was awarded Horse of the Year. Sefton's rider at the time of the bombing, Michael Pedersen, survived but he told his doctor that he was suffering from post-traumatic stress disorder; after splitting from his wife, he committed suicide in September 2012 after stabbing to death two of his children. A memorial marks the spot of the Hyde Park bombing; and the troop honours it daily with an eyes-left and salute with drawn swords. A plaque commemorating the victims of the second attack stands in Regent's Park. The event was alluded to in the 1983 Pink Floyd
