The U.S. military says a rocket that landed within several hundred yards of U.S. troops at a base in northern Iraq may have contained mustard agent. No one was hurt in the attack on Qayara West air base, according to a U.S. military official who discussed details on condition that he not be identified. He says a small group of U.S. soldiers who inspected remnants of the rocket found a black, oily substance on a fragment of metal. An initial test of the substance showed it contained residue of mustard agent, but a second test was negative. The fragment has been sent to a laboratory for further testing.
