A bus carrying students from a Japanese school in the city of Suzhou in China's Jiangsu province were attacked by a man believed to be Chinese on Monday. The incident left two Japanese people injured and one Chinese woman in critical condition.

Officials at the Japanese consulate general in Shanghai said the man was armed with what appeared to be a knife. The attack took place when the bus transporting children from the school arrived at a bus stop.

A Japanese mother and her child, who were at the bus stop, sustained non-life threatening injuries and were taken to a hospital. A Chinese bus attendant was in critical condition after she was stabbed.

The man was taken into custody and is being investigated by authorities.

The bus stop is located in a residential area about one kilometer north of the Japanese school. There is an apartment complex nearby with many Japanese residents.

The school decided to close on Tuesday as a precautionary measure.

The Japanese consulate general dispatched officials to the site to collect further information. It also asked local authorities to step up security and put measures in place to prevent a recurrence.
