BAGHDAD, Iraq (AP) _ Fifteen U.S. hostages are scheduled to be freed by Iraqi authorities on Saturday and flown home from Baghdad with boxing legend Muhammad Ali.

Ali, the former world heavyweight boxing champion, has been in Baghdad more than a week with two aides and members of the Coalition to Stop U.S. Intervention in the Middle East. Ali met with President Saddam Hussein this week for about an hour and was told he would be able to take 15 hostages home.

Ali's spokesman, Jaber Mohammed, said Friday that Ali might return later this month to Baghdad to seek the release of more Americans, hundreds of whom are being held as ''human shields'' at military and industrials sites in Iraq and Kuwait to ward off possible attack by multinational forces in the gulf..

Here is a list of those expected to be released, according to Ali associate Arthur Morrison:

George Charchalis, Reno, Nev.
