Coronavirus: two Diamond Princess passengers die as Japan defends quarantine

US says efforts to contain spread 'may not have been sufficient' as Japanese health minister argues 'we've been doing our best'

Two passengers who were onboard the quarantined Diamond Princess cruise liner have died after being diagnosed with Covid-19, Japan's health ministry said on Thursday.

The victims - the first people connected to the ship to have died - were an 87-year-old man and an 84-year-old woman, both of whom had pre-existing medical conditions, the public broadcaster NHK said, adding that the man had been hospitalised on 11 February and the woman the following day.
