Indonesian officials say at least 17 people have been killed and 3 more remain missing following a flash flood near a popular tourist destination.
A group of 70 university students and their guides were visiting the Dua Warna Waterfall in North Sumatra when a surge of water came over one of the falls.
A rescue team is continuing the search for the missing.
"The search will be focused to three main streams of the river in the villages of Rambunan, Dere and Ujung Deleng. Those are around three kilometers far from the waterfall," Darwin Surbakti, head of a local police force, told reporters on Monday.
Flash floods are common during monsoon season in Indonesia, which most years ends in April.
