Expo 2020 Dubai, the huge world fair that opened last week, on Sunday revised up the number of worker deaths to six to include COVID-linked and construction-related fatalities but said it could not say whether more had died from other causes.

The state organiser disclosed three people had died after contracting COVID-19 in addition to the previously announced three construction-related fatalities among 200,000 people who have worked on Expo in the past six years.

...... Asked by Reuters if there had been other deaths, including whether workers had died off-site from other causes, executives repeatedly declined to say, referring queries to authorities.

.... Dubai's media office did not respond to a request for comment.
