Construction sites across Melbourne have been abruptly shuttered after labourers rioted against new vaccination requirements in Australia's second-largest city, reports AFP.

Sites will be closed for two weeks, in what authorities describe as a response to “widespread non-compliance” with Covid-19 regulations and violent protests.

More than 100 construction workers in high-visibility vests brawled and smashed union office windows in central Melbourne on Monday, voicing their anger at the vaccine requirement.
