Azahari Husin, one of the suspected masterminds of the 2002 Bali
attacks and other bombings in the region.
Dulmatin is not thought to have had any formal scientific
training, but he appears to have gained significant technical
skills, supposedly under the guidance of Azahari.

other JI operatives, notably Umar Patek, have formed an alliance
