Rescuers saved more than 230 people aboard an Indonesian passenger ferry that sank Sunday in rough waters off Sumatra island, but at least 15 people have died, officials said. Search operations were called off after nightfall for the unknown number of passengers still missing.
A second ferry was still stranded in nearby waters after running aground, but all its passengers were said to be safe.
The ship sank about 30 minutes after huge waves hit its bow and water started seeping in, according to a report from the ship's captain, said Lt. Col. Edwin, the local navy chief.
Passing boats picked up dozens of those rescued and took them to nearby islands for medical treatment.
