Anti-terror police have found bombs, explosive materials, detonators, nails and books on jihad (holy war) on the island of Sulawesi, where police have reported increased militant activity in recent months.
"A total of 20 pipe-bombs and a 16-kilogram (35 pound) bomb housed in three Tupperware containers stuck together were found," said national police spokesman Boy Rafli Amar, adding the raids took place in the southern district of Enrekang.
