JAKARTA (AFP) - At least two people were killed and four injured after a possible bomb blast Saturday in an area in Indonesia's East Java that was being monitored by an anti-terrorist unit, police said.
"So far two people are dead. Twelve houses are damaged, including three badly destroyed, so we can say it was a big explosion, but we will confirm after more extensive investigation," national police spokesman Sisno Adiwinoto said.
"We found aluminum foil around the blast scene, so it's possible that this came from a bomb, but we cannot confirm yet what type," he told ElShinta radio.
The blast occurred in Pasuruan, a town about 50 kilometers southeast of Surabaya, Indonesia's second largest city.
Asked about whether the blast may have been related to Islamic militant activity, he said Indonesia's anti-terror unit, Detachment 88, had "been monitoring activities in the area, but I cannot confirm specifically the whereabouts, so let's just wait."
The owner of the house where the blast originated was being held for questioning, he added.
