Indonesian rescuers recovered the bodies of at least 17 people who were swept away in flash floods or buried under tons of mud and rocks that hit hilly villages on the country’s main island of Java, officials said Tuesday.

In December, 10 people were killed in flash floods that hit hilly villages on the country’s main island of Java. In the previous month, flash floods and landslides in North Sumatra province killed at least 29 people.

The death toll from flash floods and landslides in Pekalongan, Central Java, has risen to 19, with two more bodies found on Wednesday (Jan 22), according to Indonesia’s National Disaster Management Agency (BNPB).
