"With great sadness we confirm that three Americans were killed in the attack at CURE Hospital," said a statement posted on the Embassy's Twitter page. "No other information will be released at this time."
The shooting was the latest in a string of deadly attacks on foreign civilians in the Afghan capital this year.
Two of the dead Americans were a father and son, Minister of Health Soraya Dalil said, adding that the third American was a Cure International doctor who had worked for seven years in Kabul.

Dalil said an American nurse also was wounded in the attack.
