The war in Iraq has brought new dangers to journalists who are being targeted by extremists - A third of the 90 journalists killed in 2007 died in Iraq

Journalists killed in the pursuit of news are being honored at Washington's newly opened Newseum, a museum dedicated to the news industry. 

The memorial is a towering wall of photographs and brief biographies of fallen journalists. 

For producer Tabinda Naeem, Ruth Reader explores the exhibit and what it takes to be a journalist in dangerous areas of the world.
