The White Helmets typically have operated in opposition-held areas across Syria, places where government services are nearly non-existent, voluntarily risking their lives to save hundreds of civilian lives during relentless government airstrikes and bombardments. "I therefore authorized their transfer via Israel to other countries as an important humanitarian gesture", Netanyahu said.
"Fantastic news that we - United Kingdom and friends - have secured evacuation of White Helmets and their families - thank you Israel and Jordan for acting so quickly on our request", tweeted British Foreign Secretary Jeremy Hunt.
The group, known officially as Syria Civil Defence, has been widely hailed in the West and credited with saving thousands of people in rebel-held areas during years of bombing attacks by Damascus and its allies.
The Syrian regime launched a large offensive in June that has retaken the rebel-held areas in Dara'a and Quneitra bordering Jordan and the Golan.
Some 422 people, including women and children, crossed from Syria into the Israeli-controlled Golan Heights before travelling on into Jordan - an nearly unprecedented display of military and diplomatic co-operation between Israel and an Arab state.
The military said its actions did not reflect a change to Israel's non-intervention policy in Syria's war, now in its eight year, where all the warring parties are considered hostile.
The group receives funding from a number of governments, including Britain, Germany and the United States.
The White Helmets are western-funded and gained worldwide acclaim in 2016 when a United Kingdom documentary on the group won an Oscar.
The White Helmet members and their families will be held in a "restricted area" of Jordan.
The United States and other Western governments have funded their work, and a Netflix film, "The White Helmets", won an Academy Award previous year for best short documentary.
British Foreign Secretary Jeremy Hunt and International Development Secretary Penny Mordaunt confirmed the operation in a joint statement that praised the "brave and selfless work" of the group.
"The civilians were subsequently transferred to a neighboring country", the Ministry of Foreign Affairs stated.
The capture of a string of villages, announced by the army on Saturday, comes as evacuation of rebels and their families resumed for the second day from villages along the Golan frontier towards rebel-controlled northern Syria.
"White Helmets have been the target of attacks and, due to their high profile, we judged that, in these particular circumstances, the volunteers required immediate protection".
