A Chinese film director, his sister, mother and father have all died from the coronavirus, the latest high-profile victims of the disease in Wuhan, the city at the centre of the outbreak.
The director sent a deathbed message to friends, describing his grief and sending love to his son in London.
An environmental activist and his wife are also thought to have been killed by coronavirus, although they were not tested for the disease.
