The number of missing persons rose to 27 as landslides struck Indonesia's West Java province over the weekend, and the death toll remained 13, a senior disaster official said on Monday.

The landslides at Cihanjuang Village in West Java, about 150 kilometers southeast of the capital Jakarta took place at 4 p.m. (0900 GMT) and 7:30 p.m. on Saturday, Indonesian National Board for Disaster Management spokesman Raditya Jati said in a statement.

"When search and rescue operation for the victims was underway, suddenly other landslides occurred and buried several rescuers," Raditya added.

The landslides took place at 7:30 p.m. local time, among those buried by mud and rocks were the head of the emergency unit of the BPBD in the district and military commander in Cimanggung sub-district, Budiman said. 

"This is because the condition of the soils on the scene is unstable," he added. 

A total of 18 houses were destroyed by the landslides, leaving 18 people injured, some of whom were being treated at the health clinic in the village, Budiman added. 

As search for the missing people resumed on Sunday morning, three heavy machinery equipment were deployed with over 500 rescuers involved in the operation
