Angry crowds burned down the British Embassy in Dublin in protest at the shooting by British troops of 13 civilians in Derry, Northern Ireland on Bloody Sunday (1972) and in 1981 protesters tried to storm the British Embassy in response to the IRA hunger strikes of that year. In 1978, the European Court of Human Rights (ECHR) trial "Ireland v. the United Kingdom" ruled that the techniques used in interrogating prisoners in Northern Ireland "amounted to a practice of inhuman and degrading treatment", in breach of the European Convention on Human Rights.
