Relatives of Wuhan's coronavirus dead said Chinese authorities have deleted their social media group and are pressuring them to keep quiet while a World Health Organization team is in the city to investigate the pandemic's origins.
Scores of relatives have banded together online in a shared quest for accountability from Wuhan officials who they blame for mishandling the outbreak that tore through the city one year ago.
The effort has thus far been thwarted by official obstruction, monitoring of social media groups and intimidation, say next-of-kin.
But pressure has escalated in recent days, apparently to muzzle any criticism and avoid embarrassment during the highly sensitive WHO investigation.
