JAKARTA, Indonesia – A pair of bombs exploded at a traffic police post in Poso, Central Sulawesi, early Monday (October 22nd), injuring three people, including two police officers, local media reported.

According to witnesses, the first explosion drew a security guard and two police officers over to help. That is when the second larger bomb exploded, loud enough to be heard 3km away, The Jakarta Post reported. The bombs, thought to be planted behind the police post, demolished it.

"We haven't figured out who's responsible," National Police spokesman Boy Rafli Amar said, according to Tempo.co.

The Jakarta Globe reported that four hours before the blasts, a church in Madale subdistrict, Poso, was torched. Tempo.co quoted Poso Police Chief Eko Santoso as saying these incidents might have been an attempt to divert attention as police prepare to attack an alleged terrorist camp in the Tamanjeka Mountains.
