German authorities in the state of North Rhine-Westphalia have reimposed lockdown restrictions in two districts after a spike in cases, with more than half a million people affected.
One area is home to a meatpacking plant where more than 1,500 workers have tested positive.
State premier Armin Laschet said the “preventative measures” in Gütersloh district would last until 30 June.
Neighbouring Warendorf district has also seen restrictions return.
The state’s health minister, Karl-Josef Laumann, announced the second lockdown just hours after the first, saying further measures were needed “in order to protect the population”.
