Indonesian authorities deployed navy ships and helicopters Friday in the intensified search for 29 people still missing almost two days after a ferry sank near the tourist island of Bali. But the search was later suspended because of poor visibility.

Indonesian rescuers were searching for 29 people who remained missing Thursday after a ferry sank and six people died the previous night near Indonesia’s resort island of Bali.

The ship was carrying 65 people when it sank on its way to the Indonesian resort island, a popular tourist destination.
