Domestic or foreign?

On Friday, the White House said that anthrax found in a letter sent to Senate majority leader Tom Daschle may have been produced within the United States.

Spokesman Ari Fleischer said scientific advisers had concluded that "a PhD microbiologist in a sophisticated laboratory" could have been behind the outbreak.

But he added: "It does not rule out that it could be state supported, or that it comes from a foreign location."

On Friday, ABC television quoted three anonymous sources as saying that intial tests on the letter sent to Mr Daschle showed a chemical that is typical of Iraq's biological weapons' programme.

The Washington Post, quoting sources close to the anthrax investigation, said that only the US, Iraq and the former Soviet Union were known to have developed these kind of additives.

Officials have no evidence of a link to those who planned the 11 September attacks, but President George W Bush says he "wouldn't put it past" Saudi-born militant Osama Bin Laden, who has been named as the prime suspect.
