NPR has ended its contract with Juan Williams, one of its senior news analysts, after he made comments about Muslims on the Fox News Channel．

NPR said in a statement that it gave Mr． Williams notice of his ending in this organization on Wednesday night．

The move came after Mr． Williams, who is also a Fox News political analyst, appeared on the “The O’Reilly Factor” on Monday． On the show, the host, Bill O’Reilly, asked him to respond to the idea that the United States was facing a “Muslim dilemma（窘境）．”Mr． O’Reilly said, “The cold truth is that in the world today jihad（圣战）, helped and encouraged by some Muslim nations, is the biggest threat on the planet．”

Mr． Williams said he agreed with Mr． O'Reilly．

He continued: “You know the kind of books I've written about the civil rights movement in this country． But when I get on the plane． I got to tell you, if I see people who are in Muslim clothing and I think, you know, they are identifying themselves first and known as Muslim． I get worried． I get nervous． ”

Mr． Williams also made reference to the Pakistani immigrant who was guilty this month trying to plant a car bomb in Times Square． “He said the war with Muslims, America's war is just beginning, first drop of blood． I don’t think there’s any way to get away from these facts,” Mr． Williams said．

NPR said in its statement that the remarks “were inconsistent with our editorial standards and practices, and weakened his reputation as a news analyst with NPR”

The public radio organization said it thanked him for many years of service． Mr． Williams did

not immediately respond on Wednesday night to an e-mail seeking comment．

Mr． Williams' contributions on Fox raised eyebrows at NPR in the past． In February 2009, NPR said it had asked that he stop being identified on “The O’Reilly Factor” as a “senior correspondent for NPR,” even though that title was accurate．
