Shoko Asahara, founder of the doomsday cult Aum Shinrikyo and mastermind behind the deadly 1995 nerve gas attack in the Tokyo subway system — and a number of other horrific crimes in the 1980s and '90s — was executed on Friday, Justice Minister Yoko Kamikawa confirmed.

She also confirmed that six other condemned Aum members — Tomomasa Nakagawa, 55, Kiyohide Hayakawa, 68, Yoshihiro Inoue, 48, Masami Tsuchiya, 53, Seiichi Endo, 58, and Tomomitsu Niimi, 54 — were also executed.

In total, Asahara, 63, whose real name was Chizuo Matsumoto, was found guilty for his role in 13 crimes that led to the deaths of 27 people, a figure that later was increased to 29. In the Tokyo subway attack, 13 people were killed and more than 6,000 injured.
