An artillery shell containing a small amount of the nerve gas sarin has exploded in Iraq.
Brig Gen Mark Kimmitt said the blast had caused a small release of the substance and two people had been treated for exposure to the agent.
The substance was found in a shell inside a bag discovered by a US convoy a few days ago, he said.
It appears to be the first evidence of nerve gas existing in Iraq since the start of the US-led war last year.
