ATHENS (AFP) - Greece announced a new coronavirus death on Sunday (March 15), the country's youngest fatality, bringing the toll to four, while police arrested citizens that defied a lockdown.

The 53-year-old man, who had been in intensive care, died early on Sunday, the director of the AHEPA Hospital, Dr Panagiotis Panteliadis, told the Athens News Agency.

He had been working in a medical laboratory in the northern city of Kozani.

On Saturday, a 67-year-old man died on Zakynthos island and a 90-year-old man died in the northern city of Ptolemaida.

The first fatality had been a 66-year-old man in Patras on Thursday.

All men had existing health problems.

Greek authorities on Saturday said that an additional 38 patients had been infected by the new coronavirus, raising the total to 228.

They also said that only people with pneumonia symptoms and belonging to vulnerable groups would now be tested in public hospitals.

Greece is suspending remaining flights to and from Italy, and closing beach resorts - thwarting attempts by Greeks hoping to enjoy the fine weather there after bars and restaurants were closed.

Supermarkets, pharmacies and medical facilities have been allowed to stay open as well as shops and boutiques.

But crowd controls for supermarkets are to start Monday, when only one person per 10 square metres will be allowed.
