Jakarta – Two people were killed and a house torched in fresh violence between two ethnic groups in the Indonesian province of West Kalimantan, police said Tuesday.

"Two people were killed yesterday [Monday] in Pemangkat subdistrict 30 kilometers north of Sambas at three in the morning," Sergeant Major Pranoto of Singkawang district police in Sambas told AFP.

Pranoto said the two victims were immigrants from Madura island, adding that one died of stab wounds and the other of bullet wounds. "I can't say that the situation is safe now. Violence may break out at midnight," he said.

Violence between Madurese and ethnic Malays first erupted on February 21 when a Madurese refused to pay the fare on a public transport vehicle in Tebas. The fare collector, from the Malay community, insisted that he pay.

The Madurese later went to the collector's village of Semparuk and attacked and seriously wounded him. The Malay community responded by torching 20 houses in Tebas.

A mob also attacked a cabin housing road workers and killed two people there. A third man found dead in Tebas is also believed to have been killed by a mob.

At least 12 people have been killed and 65 houses burned in the violence involving Malay and Madurese ethnic groups since mid-February.
