A survivor of the March 1995 sarin gas attack on Tokyo's subways by the Aum Shinrikyo religious cult told a Tokyo District Court session on Thursday that the cult's founder should be sentenced to death for the crime.

The 67-year-old man, testifying as a witness in the trial of Aum founder Shoko Asahara, said all others responsible for the attack -- which killed 12 people and injured more than 5,000 -- also deserve to be executed.

It was the first time a victim of the incident has testified publicly about his feelings at Asahara's trial.
