At least 18 people were trapped under a building that collapsed in central China, officials said on Saturday local time, as rescuers pulled apart the rubble brick by brick in an effort to reach survivors.
The building, which housed a hotel, apartments and a cinema, caved in on Friday afternoon in Changsha city, Hunan province, leaving a gaping hole in a densely built street front.
It was not clear if authorities believed the people who could not be contacted were also under the rubble.
City authorities are yet to release details of casualties but said five people were rescued from the structure overnight.
