A tanker struck a New Orleans river cruise with 129 passengers on board on Friday, partially submerging the boat.
Rescues were under way on the Mississippi River, officials said in the US state of Louisiana.
Authorities did not immediately release whether there were injuries or deaths.
Video from the scene showed the much larger Atlantic Asphalt tanker hit the paddlewheel cruise boat while it appeared to be docked as metal and glass crashed and crunched.
More than a dozen people in life jackets…
