A 100kg Soviet aerial bomb was defused and another bomb part was lifted by members of the army bomb squad near Chain Bridge in Budapest before noon on Sunday.
After the first bomb was defused, a second, 250kg Soviet bomb was found but it did not contain a fuse, a bomb squad spokesman said.
Both devices have been transported by barge to the army’s central storage facility where they will be destroyed, he added.
During the operation a 300m area, including several busy roads, was evacuated.
Renovation works on the bridge are currently under way.
