An Iraqi army unit with US and Australian advisers came u nder an ISIS chemica attack in the western part of the Iraqi city of Mosul on Sunday.
According to CBS News national security correspondent David Martin, the alleged mustard agent attack resulted in injuring 25 Iraqi soldiers. No American or Australian troops were injured by the toxic agent.
However, no official identification of the agent used in the attack has been released.
The ISIS chemical attack in western Mosul was the second in a row. Earlier, reports appeared that ISIS used a toxic gas against Iraqi troops in the al-Abar neighborhood in western Mosul.
It’s important to note that the ISIS reportedly uses self-made chemical weapons in Iraq.
Meanwhile, Washington denies that any militant group could make chemical weapons in Syria and de-facto argues that the only Syrian government could be responsible for any chemical attacks.

Damn.

How do you respond to this?  As far as making home made chemicals?  I've done it by accident and almost killed myself breathing in fumes from common household cleaners.

The response to this incident will be interesting.
