DHAKA, Bangladesh — At least 26 people died and several others were missing on Monday after an overcrowded speedboat collided with a sand-laden bulk carrier and sank on the Padma River in Bangladesh, the police said.

“Rescuers found 26 dead bodies, and some still could be missing,” said Miraj Hossain, a senior police official of the central Madaripur District, where the accident occurred.

Five people were rescued and sent to a hospital, he said.

Hundreds of people die each year in ferry accidents in Bangladesh, a low-lying country that has extensive inland waterways and lax safety standards.

It was the second fatal maritime accident in one month. On April 4, a collision between a cargo ship and a small ferry killed 27 people and left more than a dozen others swimming for their lives in central Bangladesh, the latest in a long history of disasters on the country’s heavily trafficked waterway.
