Tokyo subway sarin attack

The Tokyo subway sarin attack ( was an act of domestic terrorism on 20 March 1995, in Tokyo, Japan, by members of the cult movement Aum Shinrikyo. 13 people were killed. 
The group had already carried out several assassinations and terrorist attacks using sarin, including the Matsumoto sarin attack nine months earlier. They had also produced several other nerve agents, including VX. The cult had attempted to produce botulinum toxin and had perpetrated several failed acts of bioterrorism.
In the raid following the attack, police arrested many senior members of the cult. Police activity continued throughout the summer, eventually arresting over 200 members, including Asahara himself. Thirteen of the senior Aum management have been sentenced to death, with many others given prison sentences up to life. Leader Shoko Asahara was executed in July 2018.
Executions.
On July 6, 2018, Asahara and six other Aum Shinrikyo members were executed by hanging. Japan's Justice Minister Yōko Kamikawa stated that the crimes "plunged people, not only in Japan but in other countries as well, into deadly fear and shook society to its core". Amnesty International criticized the use of the death penalty. While executions are rare in Japan, they have public support according to surveys. There were 13 members on death row at the time:
