A former senior member of the Aum Shinrikyo doomsday cult that perpetrated the deadly Tokyo subway sarin attack in 1995 said just moments before his execution last week that he did not foresee such an ending, but remained calm and thanked his parents, an informed source said Friday.

"I didn't expect things to turn out this way," Yoshihiro Inoue was quoted as saying shortly before being executed on July 6 along with cult founder Shoko Asahara and five other senior members.

Inoue, 48, was one of Asahara's closest aides and acted as a general coordinator of the group, which used the nerve agent to attack the subway system in March 1995, killing 13 people and injuring over 6,000. He was sentenced to death in 2004 by the Tokyo High Court and filed an appear for a retrial in March.
