Indonesian rescuers are searching for passengers trapped in a minibus buried in mud after flash floods and landslides hit several locations in North Sumatra province, killing at least 27, an official said on Thursday.

Indonesian officials say rescuers have recovered 16 bodies under tons of mud and rocks or that were swept away in flash floods that hit mountainside villages on Sumatra Island.

Rescue workers in western Indonesia used heavy equipment on Tuesday to dig out from weekend flooding and landslides that have killed at least 20 people, the national disaster agency said.
