The fourth part of "News War"looks at media around the globe , including the new Arab media and its role in the clash between the West and Islam, and the dangers journalists worldwide face - including death, jail and exile -  to tell their stories.

On Tuesday, March 27, FRONTLINE/World will conclude the "News War" series with a 60-minute report about global media. In the lead story, "War of Ideas,"correspondent Greg Barker investigates new Arab media and its role in both mitigating and exacerbating the clash between the West and Islam. Focusing on Al Jazeera and how it has changed the face of a once-parochial and tightly controlled Arab media, Barker reports on Al Jazeera's growing influence around the world.

The second story, "Requiem,"pays tribute to reporters from across the globe who have been killed, jailed or exiled for daring to speak truth to power. Last year was one of the deadliest years on record for journalists, and most did not die in combat. They were deliberately targeted, hunted down and murdered, often in their homes or offices, for investigating corruption, crime or human rights abuses. As the need for fair and accurate news coverage increases, FRONTLINE/World looks at the dangers journalists confront to tell their stories.
