The report is based on statements from U.S. officials, which are generally considered credible but may reflect a specific governmental perspective.

Several U.S. officials said on Wednesday that the Islamic State group, ISIS, likely targeted the Qayyarah base, where Iraqi and American forces are stationed, with a missile or artillery shell carrying mustard gas. According to CNN, U.S. officials state that these chemicals were likely fired at the base on Tuesday, and initial tests by American forces indicate that the substance used was 'mustard gas.' This base is located south of Mosul, where Iraqi forces are preparing for the final assault to retake the city from ISIS. The report indicates that no American personnel were harmed in this chemical attack. In this context, one U.S. official emphasized that the chemical agent had a 'low concentration' and was 'rudimentarily weaponized.' Meanwhile, another U.S. official referred to the attack as an 'ineffective' action. The report states that American forces have tested the materials used in this attack twice so far. According to CNN, U.S. defense officials said they were anticipating chemical attacks from ISIS forces due to the Iraqi army's preparations for the Mosul liberation operation. Hundreds of American troops are using this base to support Iraqi forces' operations. CNN reports that the U.S. has repeatedly bombed locations believed to be used by ISIS for mustard gas production. U.S. officials emphasize that producing mustard gas is easy, which is why any discovered production sites are targeted. President Barack Obama expressed hope on Monday after meeting with Iraqi Prime Minister Haider al-Abadi in New York that progress would be made in liberating Mosul by the end of this year. Mosul is considered Iraq's second-largest city and has been under the control of ISIS since the summer of 2014. The U.S. president also stated that this battle would be 'difficult and challenging' as Mosul is a large city where ISIS has deeply entrenched itself. Obama stressed that once the Mosul liberation operation is completed, it is essential to rebuild the city to prevent extremist and militia forces from returning.
