Israel’s health ministry said Saturday four people had tested positive for the novel coronavirus strain first detected in South Africa, with the British variant already recorded.
The cases were discovered after travellers arriving from South Africa were tested.
The strains that emerged in Britain and South Africa are potentially more infectious than other variants of the virus.
Amid surging cases, Israel last month reimposed a national lockdown and on Friday tightened restrictions after the daily caseload remained high.
Israel has launched a nationwide vaccination programme and more than 70 percent of Israelis over the age of 60 have received the first dose, with 1.7 million jabs administered, according to the health ministry.
Prime Minister Benjamin Netanyahu announced on Thursday that he had signed a deal for enough doses of the Pfizer-BioNTech vaccine for all Israelis over 16 to be innoculated by the end of March.
Israel, with a population of nine million, has recorded over 3,600 deaths from the Covid-19 disease.
