Indonesian police say at least eight people have been killed and 45 injured in a bomb attack at a market in the Central Sulawesi province.
The bomb exploded in a largely Christian part of the town of Palu.
A local police spokesman said that a bomb squad unit had defused a second device near the site of the blast.
The Indonesnian President, Susilo Bambang Yudhoyono, has condemned the attack and ordered an investigation into whether the bombing is related to the previous attacks in the region.
On May 28, twin bomb blasts tore through a busy market in the largely Christian town of Tentena in the province, killing 19 people and injuring at least 40.
