Four more Russian boxers - Edmond Khudoyan, Dmitry Dvali, Vsevolod Shumkov and Imam Khataev - won bronze medals.

In October last year, the IBA announced that Russian and Belarusian boxers could compete with their national symbols, and under their own flag.

Last week Russian judoka Arman Adamian, competing as a neutral, won gold in the men’s under-100 kilograms category at the World Judo Championships in Doha, Qatar.

Afterwards Putin congratulated him on his success saying Adamian had "convincingly confirmed your leadership qualities, demonstrated your character and will, and wrote a bright page in the victorious chronicle of the national judo school."
