Four people were wounded when a bomb exploded near police headquarters in the troubled town of Poso in Central Sulawesi province in Indonesia.

The bomb exploded inside a public minibus outside the Poso main market. The minibus was just 10 metres from the town's district police headquarters. Another public minibus was also damaged.

Poso district has been ravaged for over two years by intermittent violence between members of the Muslim and Christian communities. The conflict has left about 1,000 people dead and forced hundreds of thousands to flee their homes.
