Coalition forces have taken custody of the Iraqi scientist known as "Dr. Germ" for her work in making biological weapons, according to the Pentagon. Defense officials also said they had field reports that the head of Saddam Hussein's military has been captured.
American officials were hoping the latest Iraqis captured might provide information about Saddam's regime and its unconventional weapons programs, though former Iraqi leaders previously taken into custody have largely continued to deny the country had such weapons.
The scientist, Dr. Rihab Rashid Taha, had been negotiating her surrender for days and turned herself in over the weekend, said Maj. Brad Lowell of the U.S. Central Command.
U.N. weapons inspectors nicknamed Taha "Dr. Germ" because she ran the Iraqi biological weapons facility where scientists worked with anthrax, botulinum toxin and aflatoxin. A microbiologist, Taha holds a doctorate from the University of East Anglia in Britain.
Also reported captured was Armed Forces Chief of Staff Ibrahim Ahmad Abd al Sattar Muhammad al Tikriti, Pentagon officials said, citing initial reports from the region. He is No. 11 on a list issued last month of the 55 most wanted former members of Saddam's regime and the jack of spades in a card deck issued to troops looking for regime leaders.
No details of his capture were available.
Taha is not on the list of the 55, but among 200 Iraqis that Defense Secretary Donald H. Rumsfeld has said are sought but who have not all been named publicly.
Taha once said in a radio interview that Iraq was justified in producing germ weapons for its self- defense.
American forces have been trying to capture her and last month raided her Baghdad home, carrying away boxes of documents but not finding her or her husband.
Taha is married to Amer Rashid, who held top posts in Saddam's missile programs and was oil minister before the war. Rashid surrendered to U.S. forces April 28, 12 days after that Baghdad raid. The couple was married in 1994 and has a young daughter.
Rashid was the six of spades in the deck of cards.
With her detention, the United States has now acknowledged capturing at least 21 of the 55 most wanted; at least one is believed to have been killed in an air strike.
