The New York trial of Osama bin Laden's son-in-law and al-Qaida spokesman after the September 11 terrorist attacks is set to resume with the airing of testimony from a London resident who says he participated in a 2001 shoe-bomb plot.

Saajid Badat will testify live via videotape Monday from London about his experiences with al-Qaida after the attacks that demolished the World Trade Center.

Prosecutors are using his testimony to show that Sulaiman Abu Ghaith knew of al-Qaida's plans when he promised in videotapes aired worldwide that "the storm of airplanes will not abate."

Abu Ghaith faces a possible life prison sentence if he is convicted of conspiring to kill Americans and of providing material support to al-Qaida. Badat was convicted in London in the shoe-bomb plot.
