8. SOUNDBITE (English) Ari Fleischer, White House Press Secretary "There is a suspicion that this is linked to international terrorists. Having said that, the investigators also do not rule out that it could be something domestic, that it could be a lone person operating, doing this."
The Federal Bureau of Investigation (FBI) in the United States is looking for the source of the anthrax cases in the country.
There are believed to be numerous places overseas and in the U-S where the anthrax might have come from.
The F-B-I is focusing its investigation on dozens of research laboratories across the United States.
The bureau is said to be checking the backgrounds of anyone who works, or has recently worked in research facilities that store anthrax, and places that have equipment which could be used to grow and process bacteria.
The F-B-I is also looking for people who have the expertise to produce anthrax and who may be angry with the U-S government or the media, or are sympathetic to extremists groups with Middle Eastern links.
There are at least 66 facilities in the U-S that are certified to work with anthrax, including los Los Alamos national laboratory, Fort Detrick, Maryland, Northern Arizona University and Louisiana State University.
Louisiana State University says the F-B-I has already been there.
But with no firm leads, the F-B-I is casting a very wide net.
