JAKARTA - Three explosions have rocked the town of Poso in Indonesia's Central Sulawesi province, the scene of bloody Muslim-Christian clashes in the past, but police said today that no one was hurt. Second Sergeant Ridwan said the blasts at around 9 pm on Sunday did not cause injuries or serious damage. He said an investigation has been launched but declined further comment. Poso town and the surrounding district has suffered intermittent violence between Muslims and Christians since 2000 in which some 1,000 people have been killed and tens of thousands driven from their homes. Despite a peace deal last December, sporadic violence has resurfaced in recent months. A second round of government-sponsored peace talks was held last week. The government has sent more troops to boost security in Poso, bringing the number there to at least four battalions.
