On the republican side the IRA gradually changed the emphasis from open confrontations and car bombings to more carefully planned sniping attacks, together with bombing attacks in England. Bombs planted in London in March 1973 led to one death and almost two hundred injuries, the first of many sporadic but often spectacular IRA attacks in England which in the course of the troubles would take more than a hundred lives. This figure was low in relation to the overall death toll, but the political impact of attacks in Britain was often great.
