印尼渡轮沉没，仍有近180人失踪

As many as 180 people are still missing after a ferry sank in at a popular lake on Indonesia's Sumatra island earlier this week.

Authorities have deployed divers and an underwater drone to search the 1,145-square kilometer Lake Toba for the sunken vessel, which was overloaded with passengers and dozens of motorcycles when it capsized Monday evening. Lake Toba, which fills the crater of a giant volcano that erupted tens of thousands of years ago, is a popular and picturesque destination for tourists.

Eighteen passengers were rescued hours after the accident, but further rescue efforts were hampered by high winds and rough waters. Authorities believe many of the victims are still inside the ferry.

Three bodies have been pulled out of Lake Toba since the sinking.

Ferry sinkings are a common tragedy in Indonesia, a vast archipelago of 17,000 islands in the Indian Ocean, due to weak enforcement of safety regulations.
