Three people remained missing as of Monday evening after the ground gave way in downtown Guangzhou, Guangdong province, according to local authorities. Search and rescue operations are underway.
The collapse happened on Sunday morning at a construction site along metro line 11 in the city's Tianhe district, causing a street-cleaning vehicle and a scooter to plunge into a watery pit some 38 meters deep.
Two people in the vehicle were identified as a 51-year-old father and his son, 26, from Shaoyang, Hunan province.
