The new US embassy in Jerusalem will open in May 2018 to coincide with the 70th anniversary of Israel declaring independence, White House officials said.
Secretary of state Rex Tillerson has approved the security plan for the new embassy, while US congress is being notified of the impending move on Friday.
A ribbon-cutting ceremony is being planned for mid-May.
Israel proclaimed independence on May 14 1948.
The May opening marks a significant acceleration. US vice president Mike Pence had said previously the embassy would open by the end of 2019, while Mr Tillerson had said it could take years.
Initially, the embassy will consist of just a few offices inside an existing US facility in Jerusalem.
While life in Israel has returned to normal and hopes are high that Britain is set for a summer without restrictions thanks to vaccines, for billions around the world there is no such imminent light at the end of the tunnel. In the majority of countries around the globe, particularly the poorest, the vaccine rollout has barely kicked off.
That's why Jewish News, the leading source of news and opinion for the entire UK community, is throwing its full weight behind UNICEF’s VaccinAid campaign by using this platform usually reserved for encouraging donations towards our own journalism to instead urge our readers around the globe to perform the greatest mitzvah: saving a life.
We have never before done this for any charity fundraiser but it's hard to recall a campaign that affects so many people, and indeed an entire planet aching for a return to normality. Just like the Chief Rabbi and Rachel Riley, we hope to boost the mission to deliver two billion vaccines, 165 million treatments and 900 million test kits around the world by the end of this year.
Please donate as much as you can, in the spirit of the Talmudic sages: “to save one life is to save the world entire”
