Jordan said 800 people including members of Syria's controversial "White Helmets" opposition group had been evacuated Sunday from southwest Syria where the country's army is advancing against anti-government forces, with Israeli officials saying they facilitated the mission.
The Israeli military said that overnight it had completed "a humanitarian effort to rescue members of a Syrian civil organization and their families ...due to an immediate threat to their lives".
It said they were transferred to a neighboring country, which it did not identify.
On Saturday, Israeli security forces closed down roads in the occupied Golan Heights, on the Syrian frontier, ahead of the evacuation operation.
A Jordanian foreign ministry spokesman said the kingdom had allowed the U.N. to arrange the entry and passage of the 800 West-backed opposition activists, saying that their lives were in danger after a government offensive that regained opposition-held parts of southern Syria.
Jordan agreed to a request by Britain, Germany and Canada to give the White Helmet workers temporary asylum in the kingdom before settlement in the West on humanitarian grounds, spokesman Mohammad al Kayed said.
He said the aid workers would remain at a "closed" location and that Britain, Germany and Canada had agreed to resettle them within three months.
Officially called the Syrian Civil Defense but known by their distinctive white helmets, the group has been accused of being an arm of Western efforts to oust the government of President Bashar Assad as it receives millions of dollars in aid from the U.S., Canada and several European countries, while also being infiltrated by extremist and terrorist groups funded by foreign nations in as part of the regime change effort in Syria.
