The decision is pending approval by senior health officials, but Prime Minister Naftali Bennett welcomed the suggestion and has told officials to start preparing.

It comes as the head of the World Health Organisation, Tedros Adhanom Ghebreyesus, has given a warning within the last couple of hours that no country can boost its way out the pandemic.
CBS Correspondent Robert Berger spoke to Susie Ferguson.
