(CNN) -- Search and rescue efforts are underway after about 70 people were trapped in a hotel collapse Saturday night in southeastern China, officials in the city of Quanzhou said.
The hotel was used as a coronavirus quarantine center, People's Daily and other state media outlets confirmed.
Thirty-three people had been rescued from the debris by 9:30 p.m. local time (8:30 a.m. ET), the city's government said in a statement. Another 10 were rescued over the next three hours, People's Daily reported, and search efforts were ongoing.
Quanzhou is about 600 miles from Wuhan, the epicenter of the Covid-19 outbreak in China, where more than 3,000 people have died from the virus.
No fatalities have been reported in the building collapse.
It wasn't immediately clear why the building collapsed.
