U.S. soldier is among those killed in Taliban suicide blast in Kabul near the American embassy

A Taliban suicide blast in the center of Kabul has killed a U.S. soldier, a Romanian service member and at least 10 civilians near the headquarters of Afghanistan's international military force and the American embassy.

The American and Romanian service members killed on Thursday when the car bomb exploded were both NATO soldiers.

It is the second major attack this week as the Afghan government warned that a U.S.-Taliban deal on ending America's longest war was moving at dangerous speed.

The NATO Resolute Support mission, whose offices were near the blast, said the two service members were 'killed in action' but declined provide further details or release their names.
