Yahoo Inc Chief Executive Carol Bartz on Tuesday said she had been fired over the phone by Chairman Roy Bostock, a source familiar with the matter quoted an internal company email as saying.

A second source said that Bartz had been dismissed by the board and replaced, on an interim basis, by Chief Financial Officer Tim Morse.

That followed a report by tech blog AllThingsD, which cited company sources.

Yahoo representatives were not immediately available for comment.
