The US military has carried out strikes on suspected Islamic State chemical weapons sites, the Pentagon confirmed Thursday.
Information about the sites came from Sleiman Daoud al-Afari, a former chemical and biological weapons expert under Saddam Hussein's regime, who was captured by US forces several weeks ago. He has since been turned over to the Iraqi government, Pentagon spokesman Peter Cook said.
Cook declined to provide exact details about the strikes but said: "We are confident that the strikes have disrupted their capability."
US intelligence officials have said the terrorist group has carried out at least 12 mustard gas attacks and three others are likely. The attacks have resulted in deaths, but were a result of the artillery shells not the gas itself.
Still, Cook said the willingness to use the gas was cause for concern. "These are violations of international law," he said.
