A-Rosa Aqua Damage

(1:30 p.m. EDT) -- A river cruise ship and a freight barge collided on the Rhine River in Düsseldorf, Germany, injuring 11 passengers.

The accident, involving A-Rosa's 202-passenger river cruise ship, Aqua, and a cargo vessel transporting corn, happened at 10:20 a.m. local time on August. 17. Of the 179 passengers onboard, 11 were hurt and two reportedly required hospital treatment, although the injuries are not believed to be serious.

"There was an accident with one of our ships -- it collided with a ship which was transporting corn -- but the good news is there were no serious injuries to our passengers, just bumps and bruises," an A-Rosa spokesperson confirmed.

The line was unable to comment on the extent of damage or how the collision will impact the remainder of the itinerary because the damage to the ship was still being assessed. The official cause of the accident is not yet known.

"The ship is stopped in Dusseldorf at the moment. Technical experts are assessing it. The passengers are onboard. It was a full charter and was chartered by a Spanish travel group,” the line said.

Low water levels in European rivers have caused several cancellations and amendments to river cruise itineraries this summer. Last week, a stranded cargo vessel blocked river cruises on the Danube River.
