Fifteen houses were set ablaze by unidentified persons in Sigi regency of Indonesia's Central Sulawesi province as community clash erupted, local media reported here Monday.

The site is just 15 km away from Palu, the provincial capital of Central Sulawesi. Police are hunting down the perpetrators and the incident is under investigation.

"We are still probing the incident and collecting information from the site," said local police chief Sururi, quoted by the metrotv new.com as saying.

The clash between villages were triggered by a fight of two young men that developed into a mass brawl.

Hundreds of young men involved in the brawl used machetes, slingshots, and even home-made guns. Some village residents were reportedly wounded by the rock throwing as the clash raged.

A hundred of police security officers have been deployed to the border between the two villages.

Clashes between communities of neighboring villages could easily happen in Indonesia due to small problems such as words harassment of young people and so on, causing casualties sometimes.

In South Lampung, a deadly clash that claimed more than a dozen of lives in neighboring villages of the province may fade away as both community leaders have signed a peace pact on Sunday.

The deadly clash was triggered by an assault of two young women of the ethnic Lampung majority in Kalianda by young people from neighboring Balinuraga, mostly inhabited by the Balinese minority, according to the Jakarta Post.
