The Israeli military said on Sunday it had rescued members of a Syrian volunteer civil organization from the volatile border area on the Golan Heights and evacuated them to a third country.
The announcement marked the first such Israeli intervention in Syria's civil war, now in its eight year.
The military said it was an "exceptional humanitarian gesture" that was done at the request of the United States and its European allies due to "an immediate threat to (Syrians') lives."
Israeli media reported that some 800 members of the Syrian rescue organization known as White Helmets and their families were evacuated overnight. The reports say they were transferred to Jordan and would travel on from there to Britain, Germany and Canada.
The Syrian government is unlikely to fire there or carry out airstrikes for fear of an Israeli response.
The White Helmets typically have operated in opposition-held areas across Syria, places where government services are almost non-existent, voluntarily risking their lives to save hundreds of civilian lives during relentless government airstrikes and bombardments.
