12 US troops were killed in a bombing at the Kabul Airport in Afghanistan, and more than a dozen were injured. US Senator Dick Durbin says the apparent ISIS attack shows how hard it will be to sort any friends among the enemies in the country.

Durbin says the US must be squarely focused on securing the safety of US troops and remaining citizens and allies in the county. Durbin’s been told there are about 1,500 US citizens left in the county but all of them might not want to come back.
