Germany ‘likely’ to re-impose lockdown measures, says Merkel
As coronavirus cases continue to rise in Germany, Chancellor Angela Merkel has warned it is likely that the country will now need to apply an “emergency brake” and re-impose lockdown measures.
Ms Merkel said: “The situation is becoming very difficult.
“We have exponential growth…so it is good we had agreed on an emergency brake and unfortunately we will have to make use of this emergency brake.”
It comes as Germany said on Friday it was now classifying neighbouring Poland as high risk. This means that from Sunday anyone crossing the border from Poland must provide a negative coronavirus test.

Europe pushes to get vaccine drive back on track
Europe pushed to get its COVID-19 vaccination drive back on track on Friday after EU and British regulators said the benefits of AstraZeneca’s shot outweighed any risks and the World Health Organization gave its backing to it.
The end to the suspension of AstraZeneca shots by more than a dozen countries will now kick off a test of public confidence, both in the vaccine and regulators who are under unprecedented scrutiny as variants of the coronavirus spread and the global death toll climbs beyond 2.8 million.
At least 13 European countries stopped administering the shot after reports of a small number of blood disorders. More than 55 million people have received a vaccine from all manufacturers in the EU and the European Economic Area (EEA), which links 30 European countries.
