Four replacement ambulances have arrived at the north London Jewish charity targeted in an arson attack which destroyed four vehicles.
The ambulances owned by Hatzola were set ablaze in Golders Green in the early hours of Monday, leading to an investigation led by the Metropolitan Police's counter-terror unit.
No arrests have been made, but the Met said the investigation is looking at an Islamist group with potential links to Iran which has claimed responsibility for a number of similar arson incidents across Europe.
Health Secretary Wes Streeting said the government will be covering the cost of the four replacement ambulances - initially on loan - until permanent replacements can be delivered.
"The Jewish community should not bear the cost of this hatred," Streeting said.
