Two passengers from a cruise ship quarantined in Japan, have died after contracting the Covid-19 virus.
The two were in their 80s and had underlying health conditions, local media said.
At least 621 people on the Diamond Princess tested positive for the virus.
The Diamond Princess was ferrying 3,700 people.
The two passengers who died had already been taken off the ship last week and were being treated in hospitals.
But on Thursday a Japanese health ministry official responded to Mr Iwata’s criticism, saying authorities had worked hard to deal with a very complicated situation.
