Queensland in Australia is toughening its punishment for anyone caught violating coronavirus quarantines, including jailing rule-breakers for up to six months, while several US states are lockding down again — a warning that follows rising virus cases worldwide and violations of restrictions that are now being further tightened.

Queensland shut down its borders to Victoria, after its capital Melbourne saw fresh outbreaks. Melbourne recorded 270 new infections overnight, with over 4,000 cases now active across Victoria.
