AMMAN (Reuters) – Nearly 300 Syrian “White Helmet” rescue workers and their families who fled Syria for Jordan three months ago have left for resettlement in Western countries under an U.N. sponsored agreement, Jordan said on Wednesday.

In July the rescue workers who had been operating in rebel-held areas fled advancing Russian-backed Syrian government troops and slipped over the Israeli-occupied Golan Heights frontier and into Jordan, with the help of Israeli soldiers and Western powers.

Israeli Prime Minister Benjamin Netanyahu said at the time he had helped the evacuation at the request of U.S. President Donald Trump and other leaders and that there had been fears that the rescue workers’ lives were at risk.

Jordan had accepted them on humanitarian grounds after getting written guarantees they would be given asylum in Canada, Germany and Britain, Jordanian officials said.

The “White Helmets”, known officially as Syria Civil Defence, have been credited with saving thousands of people in rebel-held areas during years of bombing by Syrian government and Russian forces in the country’s civil war.

Its members say they are neutral. Syrian President Bashar al-Assad and his backers describe them as tools of Western propaganda and Islamist-led insurgents.

Jordan’s Foreign Ministry spokesman Majed al-Qatarneh said 279 of the 422 people who took sanctuary in the kingdom had left, with 93 others due to leave by Oct. 25, near the end of a three-month period the authorities had given them to stay.

Another group’s departure would be delayed for two weeks until mid-November as there were new-born babies and people receiving medical treatment among them, al-Qatarneh told Reuters.
