The search for a missing Indonesian submarine with 53 people aboard on Thursday focused around an oil slick north of the resort island of Bali with help from Australia, Singapore and other countries, Indonesia’s navy said.

The KRI Nanggala 402 was participating in a training exercise on Wednesday when it missed a scheduled reporting call. The oil slick was spotted near the starting position of its last dive, about 60 miles north of Bali.
