A landslide early Friday at a hillside tourist campground in Malaysia left 16 people dead and authorities said 17 others were feared buried at the site on an organic farm outside the capital of Kuala Lumpur. An estimated 94 Malaysians were sleeping at the campsite in Batang Kali in central Selangor state, around 50 kilometers (31 miles) north of Kuala Lumpur, when the incident occurred, said district police chief Suffian Abdullah. He said the death toll has risen to 16, including a five-year-old boy. Seven people have been hospitalized with injuries and rescuers were searching for the estimated 17 missing people, he said. Another 53 people were rescued without harm. Suffian said the victims had entered the area, a popular recreational site for locals to pitch or rent tents from the farm, on Wednesday. More than 400 personnel, including tracking dogs, were involved in the search and rescue efforts. The Selangor fire department said firefighters began arriving at the scene half an hour after receiving a distress call at 2:24 a.m. The landslide fell from the side of a road from an estimated height of 30 meters (98 feet) and covered an area of about three acres (1.2 hectare). The fire department posted photos of rescuers with flashlights digging through soil and rubble in the early hours of the morning.

Local Government Development Minister Nga Kor Ming told local media that the campsite has been operating illegally for the past two years. The operator has government approval to run an organic farm but has no license for camping activities, he said. If found guilty, Nga warned the camp operator could face up to three years in jail and a fine. Some families with young children who were rescued took refuge at a nearby police station. Survivors reportedly said they heard a loud thundering noise before the soil came crashing down. Leong Jim Meng, 57, was quoted by the New Straits Times English-language daily saying he and his family were awakened by a loud bang “that sounded like an explosion” and felt the earth move. “My family and I were trapped as soil covered our tent. We managed to escape to a carpark area and heard a second landslide happening,” he told the newspaper. He said it was surprising because there was no heavy rain in recent days, only light drizzles.

Nga, the local government development minister, said all campsites nationwide that are situated by rivers, waterfalls and hillsides will be closed for a week to assess their safety amid forecasts of downpours in the next few days. Malaysia is currently experiencing year-end monsoon rains.
