Within weeks two of the most dangerous British-born jihadi terrorists — Mohammad Sidique Khan, leader of the 7/7 suicide bombers, and Omar Khyam, leader of the so-called Crevice gang — were learning to make bombs at Malakand. Details of the party were disclosed this weekend by one of the guests, Hassan Butt, a former associate of the Islamist radicals who has turned against violence.
