Hundreds of protesters, including construction workers, gather in Melbourne to march against a new Covid-19 vaccine mandate for workers on construction sites. The march comes after the government shuttered the sites in the city and other lockdown areas in the state of Victoria following a violent protest on Monday. A huge number of police officers in riot gear tried to control the crowd as they moved through the city streets of Melbourne for several hours. Melbourne has been in strict lockdown for seven weeks, as authorities struggle to contain an outbreak of the fast-spreading Delta variant. Several clusters have been linked to construction sites, where Covid containment measures are said to be lax. IMAGES
