LUBBOCK, Texas (AP) — Twice in the days leading up to Khalid Ali-M Aldawsari’s arrest federal agents secretly searched the Saudi man’s West Texas apartment, where they say they found bomb-making chemicals as well as beakers, flasks, wiring, a hazmat suit and clocks.

They also discovered Aldawsari’s journal, handwritten in Arabic, in which he wrote that he had been planning a terror attack in the U.S. for years and that it was “time for jihad,” or holy war, court documents show.
