At least five International Security Assistance Force (ISAF) members were killed Saturday in a helicopter crash in southern Afghanistan, the ISAF said.
"Five ISAF service members died as a result of a helicopter crash in southern Afghanistan today," the statement said.
However, it did not identify the nationalities of the victims and the exact place of the incident, saying it was ISAF policy to defer casualty identification procedures to the relevant national authorities.
The statement did not mention the cause of the air crash, adding that ISAF was still in the process of reviewing the circumstances to determine more facts.
"Our thoughts and prayers go out to the families and friends affected by this tragic event," the statement added.
