Twenty tourists have been reported as missing in Tangkubanparahu tourism park in Lembang, West Bandung.
"We are searching for them in the forest. They say there is a pregnant woman [among them]. They are all from West Bandung and got lost because of heavy rains, which caused a thick fog," West Bandung firefighter's technical division chief Dadang Dahyar said Monday, as quoted by tribunnews.com.
The group comprised three men and 17 women.
Dadang said the search would take several hours, and the group would be evacuated to a temporary post near the area.
