FRANKFURT/DUESSELDORF (Reuters) - ArcelorMittal <MT.AS>, the world's largest steelmaker, has declared force majeure for its Duisburg-Ruhrort site in Germany due to the Rhine river's low water levels, a spokesman for the group said in e-mailed comments on Monday.
"The currently low water level of the Rhine means that the company has adjusted production in Ruhrort to reflect lower pig iron supplies from Thyssenkrupp <TKAG.DE>," the spokesman said.
The group is assessing the impact on orders, he added.
The move follows Thyssenkrupp's declaration of force majeure on Friday.
