NEW YORK – An award that usually is met with cheers and jubilation instead came with a moment of silence, as The Boston Globe won the Pulitzer Prize for breaking news for its "exhaustive and empathetic" coverage of the Boston Marathon bombing and the manhunt that followed.
The Globe's newsroom was closed to outsiders Monday, the day the awards were announced and a day shy of the one-year anniversary of the tragedy. Staff members marked the announcement by honoring those killed and injured.
"There's nobody in this room who wanted to cover this story. Each and every one of us hopes that nothing like it ever happens again on our watch," Globe Editor Brian McGrory told the newsroom.
The bombing last April 15 that killed three people and wounded more than 260 also led to a Pulitzer in the feature photography category for Josh Haner of The New York Times, for his photo essay on a blast victim who lost his legs.
The Times also won in the breaking-news photography category, for Tyler Hicks' coverage of the Westgate mall terrorist attack in Kenya.
The Washington Post and The Guardian won the Pulitzer Prize in public service for revealing the U.S. government's sweeping surveillance programs in a blockbuster series of stories based on secret documents supplied by National Security Agency leaker Edward Snowden.
The stories about the NSA's spy programs revealed that the government has systematically collected information about millions of Americans' phone calls and emails in its effort to head off terrorist attacks. The resulting furor led President Barack Obama to impose limits on the surveillance.
The reporting "helped stimulate the very important discussion about the balance between privacy and security, and that discussion is still going on," said Sig Gissler, administrator of the Pulitzer Prizes.
The NSA stories were written by Barton Gellman at The Post and Glenn Greenwald, Laura Poitras and Ewen MacAskill, whose work was published by The Guardian US, the British newspaper's American operation, based in New York.
Snowden, a former contract employee at the NSA, has been charged with espionage and other offenses in the U.S. and could get 30 years in prison if convicted. He has received asylum in Russia.
Snowden's supporters have likened his disclosures to the release of the Pentagon Papers, the secret Vietnam War history whose publication by The New York Times in 1971 won the newspaper a Pulitzer. His critics have branded him a criminal.
The Washington Post won a second Pulitzer in the explanatory reporting category, for Eli Saslow's look at food stamps in America.
