The setting at the Waldorf-Astoria hotel on Tuesday represented the height of refinement, but Alan Rusbridger, editor in chief of The Guardian, reminded the black-tie crowd at the annual dinner for the Committee to Protect Journalists of something it knew all too well: in many parts of the globe, its profession is under murderous assault.

“Targeting journalism has become a trend, and now the people who are harassing and killing journalists include governments as well as the people you would expect,” said Mr. Rusbridger, who, along with others, was honored at the gathering in New York.

Journalists who dig into murky and dangerous corners of the world have become accustomed to being threatened and sometimes hunted by drug lords and gangsters, but now some governments have decided shooting the messenger is a viable option. The C.P.J. reports that government officials and their allies are now suspected of being responsible for more than a third of the murders of journalists, a higher proportion than killings attributed to terrorist groups or criminal enterprises.

On the same day as the Waldorf event, three employees of news organizations were killed in Gaza by Israeli missiles. Rather than suggesting it was a mistake, or denying responsibility, an Israeli Defense Forces spokeswoman, Lt. Col. Avital Leibovich, told The Associated Press, “The targets are people who have relevance to terror activity.”
