JAKARTA: At least 15 people died after landslides and flooding in central Indonesia swept away dozens of houses and damaged roads, the Southeast Asian country's disaster agency said on Saturday.

Indonesia is prone to landslides during the rainy season, with the problem aggravated in some places by deforestation, with prolonged torrential rain causing flooding in some areas of the archipelago nation.

The landslides struck Luwu regency in South Sulawesi province on Friday just after 1 a.m., Abdul Muhari, spokesman of Indonesia's National Agency for Disaster Countermeasure, or BNPB, said in a statement.

"A total of 14 residents died due to floods and landslides in" the regency, he added.

The BNPB said more than 100 houses were seriously damaged and 42 were swept away, while four roads and one bridge were damaged.

More than 100 people were evacuated to mosques or relatives' homes, and over 1,300 families were affected, with authorities trying to evacuate them.

In another area of South Sulawesi, at least one person died and two others were injured in floods on Friday, Abdul said in another statement.

In March, flash floods and landslides on Sumatra island killed at least 30 people, with scores still missing.

A landslide and flooding swept away dozens of houses and destroyed a hotel near Lake Toba on Sumatra in December, killing at least two people.

Indonesia has suffered a string of recent extreme weather events during its rainy season, which experts say are made more likely by climate change.
