Sydney's usually bustling harbourside restaurants were shuttered and the city streets deserted Saturday as a lockdown was extended across Australia's largest city by authorities struggling to contain an outbreak of the Delta coronavirus variant. In the Rocks, a historic area dating back to the first European settlement of Australia in the shadow of the Sydney Harbour Bridge, Chris Kriketos said he felt a "really bad case of deja vu" and the area had turned back into a "ghost town". "We've been struggling to get it back from the lockdowns of last year," said the 32-year-old, whose family bakery has been in the area for nearly four decades. IMAGES AND SOUNDBITES
