The Jordanian Foreign Ministry said in a statement on Wednesday that about 300 Syrian "White Helmet" workers fled Syria for Jordan three months ago.
In July, the White Helmets, fleeing advancing Syrian government troops, 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 US President Donald Trump and other Western leaders.
Jordan had accepted them after getting guarantees that their stay would be temporary and they would be given asylum in Canada, Germany and Britain.
The White Helmets have operated in militant-held areas in recent years.
