KUWAIT (AP) _ The United States is documenting alleged war crimes committed during Iraq's seven-month occupation of Kuwait, just in case Saddam Hussein is tried before an international court one day, a senior U.S. official said Monday.

David John Scheffer, U.S. ambassador at large for war crimes issues, spoke to reporters after a two-day visit to gather evidence of murder, rape and torture allegedly committed by Iraqi troops.

In February 1991, a U.S.-led coalition liberated Kuwait, a small, Persian Gulf state between Iraq and Saudi Arabia, from the Iraqi occupation.

Scheffer said a trial of the Iraqi president would not happen soon because there was no established court to hold it in.

``It is entirely speculative when such mechanism could be established,'' he said. ``But I think our immediate priority is to establish the record in such a persuasive ... way that the international community will not be able to ignore what that evidence reveals.''

Scheffer's post was created last year to seek accountability for serious violations of international humanitarian law anywhere in the world.
