Footage from a Russian cargoship has shown how it managed to steer into a Korean bridge last week.
The 9,700-dwt Seagrand (built 1986) took a chunk out of the Gwangan Bridge as it left the southeast port of Busan on Thursday.
The master was found to be over the limit for alcohol, but claimed he started to drink after the collision, the Yonhap news agency reported.
