The victims included 31 children, said Nazrul Islam, police chief of Bangladesh's Bhola district, where the accident happened Friday.

About 10 to 15 people were missing and feared dead.

The boat had a capacity of 1,500, but was crammed with about 2,000 people who were traveling from the capital, Dhaka, to their homes in Bhola for the Muslim festival of Eid al-Adha.

The boat toppled as passengers weighted down one side to disembark, Islam said.

Police and firefighters rushed to help passengers, many of whom were trapped in the lower deck.
