Dozens hit by 'suicide gas' in Japan

A Japanese teenager has committed suicide by mixing common household cleaners, releasing fumes that made dozens of people sick, officials said.

About 100 people in Konan City, in western Japan, fled their homes after smelling the toxic hydrogen sulphide the 14-year-old girl had made.

There has been a spate of similar suicides since details of the technique were posted on the internet.

Japan has one of the developed world's highest suicide rates.

At least 30,000 people have killed themselves every year since 1998, according to national statistics.

Toxic chemical

The unidentified girl in Konan City left a note on the bathroom door of her family's flat saying "poison gas being produced", Japanese media said.

About 90 neighbours went to hospital feeling ill, including the girl's mother, who was out of the flat during the suicide but later returned.

Most people complained of sore throats but none was severely ill, officials said.
