Tanker hits river cruise boat on Mississippi River
Video from the scene showed the much larger Atlantic Asphalt tanker hit the paddlewheel cruise boat while it appeared to be docked.
A tanker has struck the American Heritage river cruise paddleboat in New Orleans with 129 passengers aboard, partially submerging the boat.
Rescues are under way on the Mississippi River, officials said.
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 lifejackets were being dragged from the 19C river on to nearby ships.
Others were standing near the railing as the other side of the American Heritage listed further into the water.
“Surreal – that’s what that was,” witness Jamie Holford told WDSU-TV.
“Fifteen minutes from impact to where it rolled over.”
The cruise ship was built in 2015 and operated by American Cruise Lines.
It is five storeys and can hold up to 150 passengers.
The American Heritage was finishing an eight-day cruise to several Mississippi River destinations in Louisiana and Mississippi.
The tanker involved in the crash specialises in carrying large quantities of asphalt and bitumen, a semi-solid substance that is often used for road construction and roofing, according to the live shipping tracker MarineTraffic.
Ships carrying asphalt and bitumen are often heated well above 120C to prevent the asphalt from solidifying on the ship, according to the maritime periodical Marine Insights.
It is not immediately clear whether the ship was carrying any materials when the crash occurred.
The 520ft (160-metre) long vessel had a final destination in New Orleans, according to MarineTraffic, and was sailing under a flag for the Marshall Islands.
