Potential threats from so-called Islamic State against Americans in Afghanistan are forcing the US military to develop new ways to get evacuees to the airport in Kabul, a senior US official said Saturday.

The move adds a new complication to the already chaotic efforts to get people out of the country after its swift fall to the Taliban.
