Germans may face a national lockdown to stop the spread of the novel coronavirus if they fail to obey instructions to stay indoors this weekend, officials said on Friday.

Germany has recorded 10,999 cases of the novel coronavirus, official data showed Thursday, with the number of new reported infections rising by 2,801 in a single day.

A 65-year-old German tourist has tested positive for COVID-19, the illness caused by the novel coronavirus, the first known case in northern Cyprus, authorities said on Tuesday.

Around 1,000 people were in quarantine in Germany's most populous state Friday, as the number of confirmed cases of novel coronavirus in Europe's biggest economy rose above 50.

A car that rammed into a carnival procession in central Germany Monday injured 52 people, including 18 children, police said, adding that the perpetrator's motive remains unclear.

At least nine people were killed in shootings targeting shisha bars in Germany that sparked a huge manhunt overnight before the suspected gunman was found dead in his home early Thursday.

Ten thousand people are expected to join a demonstration Saturday in Erfurt, capital of Thuringia state in Germany's former communist east, where far-right lawmakers last week helped install a new state premier.

German Chancellor Angela Merkel voiced a feeling of "deep shame" during her first-ever visit on Friday to the hallowed grounds of the former Nazi German death camp of Auschwitz-Birkenau, where Adolf Hitler's regime murdered more than a million people.

Merkel noted that her visit comes amid rising anti-Semitism and historical revisionism and vowed that Germany would not tolerate anti-Semitism. She said Germany remains committed to remembering the crimes that it committed against Jews, Poles, Roma and Sinti, homosexuals and others.

Chancellor Angela Merkel's government reached a deal Friday on a broad climate plan for Germany, a coalition source said, as tens of thousands of protesters rallied demanding more environmental protection.

Thousands of civil society activists are to mount a march against hate and racism on Saturday in Dresden, a week before state elections when far-right party AfD is projected to make huge gains.
