Beach town Phan Thiet with over 228,000 people began a 14-day lockdown under Directive 16 on Monday, which requires people to stay at home and only go out for necessities such as buying food or medicines or to work at factories or businesses that are allowed to open.

Phan Thiet, home to Mui Ne, a beach resort hotspot, has detected a number of Covid cases with their sources remaining unidentified, Voice of Vietnam reported.

Binh Thuan Province has recorded 667 infections in the ongoing wave that began in late April.
