WASHINGTON (Reuters) -The count of U.S. troops believed to have been killed in Thursday's Kabul blasts has increased to 12, according to U.S. officials citing initial information that can change.
Earlier a U.S. official told Reuters that at least 10 American military members were believed killed in the explosions at a gate at the Kabul airport where the United States is mounting a massive evacuation and at a nearby hotel.
