WASHINGTON — The US government has raised its terror warning status this week after the FBI issued a warning that the terror group ISIS may have access to the chemical dihydrogen monoxide (DHMO), and may be preparing to use it in attacks on US soil.

Sources say the group has used the substance to launch probing attacks on multiple US coastal cities. A recent attack in Louisiana has destroyed thousands of homes, although ISIL has not yet claimed responsibility.

"We're doing everything we can to dry up their supply of DHMO," said FBI Director James Comey. "We've been inundated by a flood of information in the past twenty-four hours, and we hope some of that will trickle down into actionable intelligence."
