Fourteen journalists killed covering the news in 2014 -- including two executed by Islamic militants in Syria -- were recognised by the Newseum, which added their names to its Washington journalists' memorial.
Among those honored were photojournalist James Foley, a freelancer who had reported for GlobalPost, Agence France-Presse and other outlets from Afghanistan, Libya and Syria, and Steven Sotloff, an American-Israeli journalist who had worked for Time and the Christian Science Monitor.
With the 14 names, the memorial will recognize a total of 2,271 reporters, photographers, broadcasters and news executives from around the world, dating back to 1837.
"It is right, and just, that we pause today in our busy lives to remember what these journalists did, and why they did it," Peter Prichard, chief executive officer of the Newseum, said at a ceremony at the news media museum.
John Foley, father of James Foley, said his son and Sotloff suffered "horrific deaths" but that John "left his mark as a wonderful human being attempting to defend our right to know, one person at a time."
For the first time in the Newseum's seven-year history in Washington, the "Today's Front Pages" exhibit was blacked out for the day to raise awareness of the threats journalists face.
Gene Policinski, chief operating officer of the Newseum Institute, said the memorial is a way to acknowledge the journalists' sacrifices.
"We are but the caretakers and guardians of this Memorial on behalf of those who ultimately require no such construct to confirm their courage and self-sacrifice," he said.
The 11 men and three women honored represent the more than 80 journalists who died while covering the news in 2014, according to the Newseum.
