Al-Qaida No. 3 says he planned 9/11

By KATHERINE SHRADER, Associated Press Writer

Khalid Sheikh Mohammed confirmed his notoriety as al-Qaida's most ambitious operational planner when, according to military transcripts, he confessed to planning and supporting 31 terrorist attacks, topped by 9/11, that killed thousands of innocent victims since the early 1990s.

The gruesome attacks range from the suicide hijackings of Sept. 11, 2001 — which killed nearly 3,000 — to a 2002 shooting on an island off Kuwait that killed a U.S. Marine.

Many plots, including a previously undisclosed plan to kill several former U.S. presidents, were never carried out or were foiled by international counterterror authorities.
