Ten children and their teacher were attacked at a train station in Germany by a perpetrator using what has been referred to as an "irritant gas".

A 39 year old man apparently approached the group and sprayed them with a yet unnamed substance. The children were initially treated at the scene, having their eyes flushed and faces rinsed. Some of them were also suffering from shortness of breath. 

An apparent chemical suicide at the Fairmont Hotel in San Jose, California, at the weekend, turned in to a full Hazmat situation when other guests in the hotel began to show symptoms of exposure.
