Israel on Sunday approved barring entry to foreign nationals and the use of controversial technology for contact tracing as part of its efforts to clamp down on a new coronavirus variant.

The Health Ministry said in a statement that the country’s coronavirus cabinet had authorized a raft of measures, including red-listing travel to 50 African countries, banning entry by foreigners and mandating quarantine for all Israelis arriving from abroad.

It also approved use of the Shin Bet internal security agency’s controversial phone monitoring technology to perform contact tracing of individuals confirmed with the new omicron variant of coronavirus in Israel.

Israeli rights groups had decried the use of the cellphone monitoring technology as a violation of privacy rights, and the Supreme Court ruled earlier this year that its use be limited.

Israeli Prime Minister Naftali Bennett said Sunday that tightening Israel’s borders will help keep the country open internally.

“Restrictions on the country’s borders is not an easy step, but it’s a temporary and necessary step,” he said at the start of the weekly Cabinet meeting.

Dr. Ran Balicer, head of the government’s advisory panel on COVID-19, told Israel’s Kan public radio that the new measures were necessary for the “fog of war” surrounding the new variant, saying it was “better to act early and strictly” to prevent its spread.

Over the weekend, Israel said it had detected the new strain in a traveler who had returned from Malawi and was investigating seven other suspected cases. The seven people included three vaccinated individuals and all were placed in isolation.

The new coronavirus variant has been detected in South Africa that scientists say is a concern because of its high number of mutations and rapid spread.

Israel, a country of 9.3. million people, has reported at least 8,184 deaths from coronavirus since the start of the pandemic. Most of its population — over 6.3 million people — has received at least one dose of the Pfizer/BioNTech vaccine, and more than 4 million Israelis have received a booster. It has more than 7,000 active cases, 120 of them hospitalized in serious condition, according to Health Ministry statistics.
