Tuesday’s sinking came a few weeks after an overcrowded ferry sank on Indonesia’s Lake Toba, one of the world’s deepest volcanic lakes, claiming more than 200 lives.
The regional disaster mitigation agency said 41 people remained missing in Tuesday’s accident. Another 69 passengers had been rescued.
The ferry was carrying an unknown number of vehicles when it began to fill with water and sink. The vessel was close to shore and the captain ran it onto a reef in a bid to help the rescue effort, a transport ministry official told Reuters.
Indonesia suffers frequent maritime accidents, with basic safety rules often flouted and vessels overloaded.
