Katie Couric will make her prime-time CBS News debut on Sept. 6 with a one-hour special tied to the fifth anniversary of the Sept. 11 terrorist attacks, the network said Monday.

"Five Years Later — How Safe Are We?" will air at 10 p.m. EDT and talk about what the government is doing to prevent future attacks and how anxiety affects Americans.

It's one day after Couric makes her debut as "CBS Evening News" anchor. She will anchor the evening news on Sept. 11 from ground zero, part of several coverage plans CBS News announced Monday to mark the occasion.

ABC News said Charles Gibson will anchor a prime-time report on the anniversary on Sept. 11. NBC News has not announced its commemoration plans.
