A book attacking US policy in Rwanda and Bosnia has won a top literary prize.
LBJ: still fascinating after 40 years
The Pulitzer Prizes, among the top literary book awards in the United States, were dominated by politics and war this year.
The prize for the best general non-fiction book was awarded to Samantha Power for her book A Problem from Hell: America in the Age of Genocide.
Ms Power, who had been a journalist in Yugoslavia during its break-up, writes a highly critical account of the failure of US foreign policy to confront the crimes against humanity in Bosnia, Kosovo and Rwanda during the 1990s.
The prize for best biography was awarded to Robert Caro for the third volume of his magnificent biography of Lyndon B Johnson, the US president who was most closely associated with the Vietnam war.

Honour for Muldoon and Middlesex

The Wall Street Journal won an award for its reporting of the wave of corporate scandals that have swept through American business in the past year.
