The EC-135 helicopter went missing in the morning and local police said that canoeists later spotted parts of the helicopter in the river.
More than 100 emergency service members, including police divers, joined the search for the crew.
A boom has been deployed in the Mulde because of kerosene leaking from the helicopter.
“The death of the crew members has affected me and the whole of the armed forces deeply. Our thoughts are with their relatives and relatives,” Pistorius said.
He added that “everything possible” would be done to investigate the circumstances of the crash.
