Five U.S. service members were killed when a helicopter crashed in southern Afghanistan, a U.S. official said early Tuesday.

The chopper went down Monday in the Daman district of southern Kandahar during a rain storm, said Jawid Faisal, a government spokesman for the province.

There was no enemy activity in the area at the time of the incident, according to a statement by the International Security Assistance Force (ISAF).

The U.S. official, who did not want to be identified, did not offer additional information about the victims. . .
