LONDON (AP) — Politician John Hume, who won Nobel Peace Prize for work to end violence in his native Northern Ireland, has died at 83. His family says he has suffered ill health for a number of years. The Catholic leader of the moderate Social Democratic and Labour Party, Hume was seen as the principal architect of Northern Ireland’s 1998 peace agreement. He shared the 1998 Nobel Peace Prize with the Protestant leader of the Ulster Unionist Party, David Trimble, for their efforts to end the sectarian violence that plagued the region for three decades and left more than 3,500 people dead. Tributes to Hume poured in from U.K. and Irish leaders past and present.
