JERUSALEM/AMMAN: Hundreds of Syrian "White Helmet" rescue workers and their families fled advancing government forces and slipped over the border into Jordan overnight with the help of Israeli soldiers and Western powers, officials said. Israeli Prime Minister Benjamin Netanyahu said in a brief video statement yesterday he had helped the evacuation at the request of US President Donald Trump and other leaders - and there had been fears that the workers' lives were at risk.

The group, known officially as Syria Civil Defense, 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. Its members, known for their white helmets, say they are neutral. But Syrian President Bashar Al-Assad and his backers, including Russia, have dismissed them as Western-sponsored propaganda tools and proxies of Islamist-led insurgents. There was no immediate response from Damascus on Sunday.

A Jordanian government source said 422 people were brought from Syria, over the Israeli-occupied Golan Heights frontier and into Jordan, down from a figure of 800 announced earlier by the foreign ministry in Amman. The evacuees will be kept in a "closed" location in Jordan and resettled in Britain, Germany and Canada within three months, the source added. A second non-Jordanian source familiar with the agreement said the original plan had been to evacuate 800 people, but only 422 made it out as operations were hampered by government checkpoints and the expansion of Islamic State in the area.

Syria and its Russian allies have launched an offensive on rebels in the sensitive southwestern border zone.

Netanyahu said Trump, Canadian Prime Minister Justin Trudeau and others had spoken to him recently asking for help in extracting the White Helmets. "The lives of these people, who have saved lives, were now in danger. I therefore authorized their transfer via Israel to other countries as an important humanitarian gesture," Netanyahu said. Trump did not mention the operation during a series of tweets yesterday. Britain hailed the evacuation, saying it and other allies had requested it. "Fantastic news that we - UK 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.

German weekly magazine Bild, which broke news of the evacuation and published footage of buses used to transport the Syrians across Golan, said 50 of them would be granted asylum by Berlin. "Humanity dictates that many of these brave first-aiders should now find protection and refuge, some of them in Germany," it quoted German Foreign Minister Heiko Maas as saying. A spokeswoman for the German interior ministry said Berlin would take in eight White Helmets plus their families. It was not immediately clear whether that amounted to the same 50 people.

A Canadian Foreign Ministry statement on Saturday said the White Helmets "have witnessed vicious atrocities committed by the Assad regime and its backers". It added: "We feel a deep moral responsibility to these brave and selfless people." Russia's embassy in the Netherlands welcomed the White Helmets' departure. "Definitely there will be less chances of new so-called #CW (chemical weapon) attacks in Syria after forced evacuation by the collective West of the notorious #WhiteHelmets," it tweeted. Damascus and its allies have accused rebels and their supporters of staging chemical attacks in an attempt to frame the government. Western powers have accused Syria of attacking rebel-held areas with illegal chemical weapons.

It was unclear how many White Helmet volunteers remained in both the Daraa and Quneitra provinces after the evacuations. But a volunteer in Daraa city, who asked to remain anonymous, said he had decided to stay despite being given the choice to leave. "It's our country and we have a right to live in it in safety," he told AFP, however adding he was among a minority who wished to remain. "We are first and foremost a humanitarian organization, not a military one, or a terrorist one as the regime alleges."

The White Helmets have rescued thousands of civilians trapped under the rubble or caught up in fighting in opposition-held zones along various fronts of Syria's seven-year conflict. Since its formation, when Syria's conflict was nearing its third year, more than 250 of its volunteers have been killed. The group's motto - "To save one life is to save all of humanity" - is drawn from a verse in the Holy Quran, although the White Helmets insist they treat all victims, regardless of religion.

Some members have received training abroad, including in Turkey, returning to instruct colleagues on search-and-rescue techniques. The group receives funding from a number of governments, including Britain, Germany and the United States, but also solicits individual donations to purchase equipment such as its signature hard hats. - Agencies
