Chinese state media said 59 people remain missing after an enormous landslide hit an industrial park in southern China and buried 22 buildings, including two workers' dormitories.
Officials said four people were rescued from the debris, three of them with minor injuries.
The official Xinhua news agency said the landslide struck Shenzhen in Guangdong province Sunday morning, covering the area in a sea of mud and triggering a gas line explosion nearby.
More than 1,500 rescue workers have been sent to the area to look for survivors. About 900 people were evacuated before the landslide struck.
Chinese President Xi Jinping and Premier Li Keqiang have ordered central authorities to send officials to assist in the rescue efforts.
The cause of the landslide is not clear, but the area has had considerable construction taking place in recent years.
