Indonesia: At least 21 killed in flash floods South Sulawesi province

At least 21 people have been killed as of Wednesday and two remain missing after flash floods hit Indonesia's South Sulawesi province, according to officials.

National Disaster Mitigation Agency spokesman Raditya Jati said search and rescue operations were underway but were hampered by thick mud covering roads and houses and continued rain fall.

Ten others were injured in the flooding, which affected six subdistricts in the province, he said. As of Wednesday evening, 2,650 people had been evacuated.

North Luwu district official Indah Putri Indriani said the flooding began Monday evening and was triggered by heavy rains that caused three rivers to overflow.

Heavy rains cause frequent landslides and flash floods in Indonesia, where millions of people live in mountainous areas or near flood plains.
