(CNN) - It's too soon to say what steps the United States will take against ISIS in Syria, President Barack Obama said Thursday.
"I don't want to put the cart before the horse," Obama said. "We don't have a strategy yet."
Obama said he's asked U.S. military leaders to prepare "a range of options" about what the United States could do to go after ISIS in Syria, which he said has become "a safe haven" for the Islamist group.
In Syria, he said, it's a political issue as well as a military one - and something regional leaders need to address.
