Israel says it has carried out an evacuation of members of Syria's White Helmets civil defence group from a war zone in south-western Syria.
He said they would be allowed to stay in Jordan for a period of time not exceeding three months.
The request for the evacuation came as the volunteers and their relatives were threatened by advancing forces of the Syrian government in the south of the country.
"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 U.S. State Department said in a statement that it welcomed the operation and renewed its call on "the Assad regime and Russian Federation to abide by their commitments, end the violence, and protect all Syrian civilians".
First on the scene for airstrikes and attacks, the group are also frequently a primary news source.
"Iranian forces and forces from Lebanon's Hezbollah movement are deployed in that sector", Observatory head Rami Abdel Rahman told AFP.
The White Helmets have been one of the few glimmers of light during the bloody and savage war that has ravaged Syria since 2011, leaving 350,000 people dead and millions more displaced.
Israeli Prime Minister Benjamin Netanyahu has stated he will meet with Russian Foreign Minister Sergey Lavrov and Chief of the General Staff Army General Valery Gerasimov in order to discuss issues concerning the Syrian conflict, TASS reports.

Over the last month, Syrian government forces aided by Russian air power have swept through southwestern Syria to consolidate government control over this strategic corner of the country that straddles the border with Jordan and the frontier with Israeli-occupied Golan Heights.
The White Helmets are a group of volunteer first responders working in areas under rebel control in Syria - providing necessary services like ambulance, medical, firefighting, and rubble clearing.
They are expected to be resettled in the UK, Germany, and Canada.
Russia's military said it had also shot down two unidentified drones that attacked its air base at Hmeimim in northern Syria on Saturday and Sunday, Russian agencies reported.
A spokeswoman for the German interior ministry said Berlin would take in eight White Helmets plus their families.
Russian Foreign Ministry stated that consultations are underway with a number of regional and worldwide countries to lift the unilateral economic sanctions imposed on Syria. The Israeli military declined comment. "Saving lives is the biggest crime we are charged with; now we are called terrorists because we save lives".
The group receives funding from a number of Western governments and individual donors.
More than 20,000 civilians have escaped bombardment on the IS-held corner in the past 24 hours, fleeing into regime-held areas, the Syrian Observatory for Human Rights said.
On June 19, Syrian government forces launched a Russia-backed offensive to retake Daraa and Quneitra provinces.
