Israel said Sunday it will reimpose a national lockdown after coronavirus cases soared, while European nations grappled with mounting infections against a backdrop of protests against restrictions aimed at reining in the pandemic.
Israeli Prime Minister Benjamin Netanyahu announced the three-week lockdown, which will hold people to within 500 metres of their homes, will start on Friday and could be extended.
The plan prompted the resignation of ultra-Orthodox Housing Minister Yaakov Litzman, who said the measures would prevent Jews from attending synagogue over the upcoming Rosh Hashanah and Yom Kippur holidays.

'Aggressive' Melbourne lockdown protest
However some countries were relaxing their anti-coronavirus restrictions.
In South Korea, authorities in Seoul said they would ease some infection control measures introduced in recent weeks after a spike in cases in the capital region, home to half the country's 52 million population.
Coffee shops, restaurants and bakeries will return to normal service while gyms and private schools can reopen.
The country largely overcame an early Covid-19 surge with extensive tracing and testing, but it has seen triple-digit daily new cases since mid-August after weeks with numbers in the 30s and 40s.

And Saudi Arabia announced it would partially lift its suspension of international flights from September 15, six months after travel curbs were imposed.
Meanwhile, police arrested dozens of participants in an illegal anti-lockdown demonstration in Melbourne on Sunday that drew around 250 people.
The protest - the city's second in as many days - saw the crowd defy stay-at-home orders to gather at the central Queen Victoria market, where they were met by a heavy police presence.
"Many protesters were aggressive and threatened violence towards officers," the Melbourne police said.
The Australia protest followed a number of demonstrations in Germany and Poland on Saturday at which thousands protested against anti-coronavirus measures.
