Three Russians among eight disqualified by IOC over failed Beijing 2008 drugs tests

Nadezhda Evstyukhina won bronze at the 2008 Olympics in Beijing in the women's 75kg weightlifting

The International Olympic Committee (IOC) has stripped more Russian athletes of medals for failing drugs tests at the Beijing 2008 Games.

Silver and bronze-winning weightlifters Marina Shainova and Nadezhda Evstyukhina have been sanctioned along with 4x400m runner Tatyana Firova.

Russia had already lost their 2008 4x400m relay silver.

A further five athletes have also been punished after their old samples were retested, the IOC said.

They are:

• Tigran Martirosyan, Armenia. Men's 69kg weightlifting - won bronze.

• Alexandru Dudoglo, Moldova. Men's 69kg weightlifting - came ninth.

• Intigam Zairov, Azarbaijan. Men's 85kg weightlifting - came ninth.

• Yarelys Barrrios, Cuba. Women's discus - won silver.

• Samuel Adelebari Francis, Qatar. Men's 100m - came 16th.

The five have had their Beijing results annulled and their sports' governing body asked to reassign any medals.

The IOC carried out more than 4,500 drugs tests at the 2008 Olympics but only nine athletes tested positive.

It has since retested more than 450 samples, using new methods to uncover banned substances that would have gone undetected at the time.

The IOC has also carried out about 250 retests on samples from London 2012.

Russian track and field athletes were banned from competing at Rio 2016 by the IAAF after widespread, state-sponsored doping was uncovered in the country.
