Internet auction giant eBay banned the sale of any items relating to the World Trade Center or the Pentagon, out of sensitivity to Tuesday's terrorist attacks.

Managers of the site took down several listings offering debris or other items purportedly from the buildings, eBay spokesman Kevin Pursglove said Tuesday evening.

As the day went on, the company decided that it would not be appropriate to allow even legitimate items related to the World Trade Center or the Pentagon, Pursglove said. The company wanted to eliminate the chance someone would try to profit from the tragedy, he said.

Items already up for sale even before the attacks -- such as dozens of postcards, posters and other collectibles related to the World Trade Center and Pentagon -- were expected to be taken down later Tuesday. The ban will last until Oct. 1, Pursglove said.
