Two people were hospitalized after a building collapsed in a central area of Sydney on Monday, emergency services said.
A spokesperson for New South Wales Ambulance said it was called to an address in Ultimo, a suburb around 2 km (1.2 miles) from the city's central business district, just before 11 a.m. local time.
Footage from Australian television network Seven showed the collapsed wall of a large building that the channel said was located near a construction site.
Fire and Rescue Acting Superintendent Peter Murray said it was a "significant roof collapse," according to the Australian Broadcasting Corporation (ABC). "[It's] very fortunate that more people weren't hurt."
"We're doing atmospheric monitoring at the moment and also looking at things like any electrical hazards, gas hazards," he said.
Two taken to hospital in serious condition
Workers assessed seven patients at the scene, of whom two were transported to hospital in serious condition after being pulled from the rubble.
According to ABC, Murray said that there were no reports of anyone missing, though that was being verified through ongoing searches and investigations of further structural damage.
ABC said that three Fire and Rescue teams were at the scene of the collapsed warehouse, which was previously approved for demolition.
