The death toll from an outbreak of coronavirus in Italy has jumped in the last 24 hours by 189 to 1,016, a rise of 23 percent, the country’s Civil Protection Agency said on Thursday.

The total number of cases in Italy, the European country hardest hit by the virus, rose to 15,113 from a previous 12,462, an increase of 21.7 percent. 

The World Health Organization (WHO) declared the outbreak a pandemic as Italy tightened its strict quarantine and the United States imposed a ban on flights to Europe.
