JAKARTA, Aug 11 (Reuters) - An explosion killed two people and injured four in Indonesia's East Java province on Saturday, police said. Police have not determined the cause of the blast that destroyed two houses in the district of Pasuruan, local police chief detective Mardiansjah told Reuters by telephone from the area. "There appear to be explosive materials at the scene. The bomb squad personnel are trying to secure the site," he said. Indonesia has suffered a wave of bombings blamed on Islamic militants in recent years.
