New York (Reuters) - Harrah's Entertainment Inc. plans to build a new land-based casino in Biloxi, its chief executive said on Wednesday, expanding its presence in the Mississippi Gulf Coast, which is still recovering from 2005 hurricane damage. "We will announce relatively soon a new project near our Grand facility, which we've been operating on a fairly limited scale since we were able to get it reopened after the storm (Katrina)," said Gary Loveman, Harrah's CEO.
