WASHINGTON (AP) — President Barack Obama says the United States doesn't know how or when chemical weapons were used in Syria or who used them.
Obama told reporters at a news conference Tuesday he's got to make sure he has the facts before deciding how to respond to evidence that chemical weapons were used.
Obama has said there is "some evidence" that President Bashar Assad's government used chemical weapons against his people. But he said that's a preliminary assessment based on intelligence information.
Obama repeated his statement that the use of chemical weapons would be a "game changer" in the region. But he said the international community has to be completely confident in the assessment.
