In a statement, Greece triple-jumper Voula Papachristou said:
I would like to express my heartfelt apologies for the unfortunate and tasteless joke I published on my personal Twitter account.
I am very sorry and ashamed for the negative responses I triggered, since I never wanted to offend anyone, or to encroach human rights."
My dream is connected to the Olympic Games and I could not possibly participate if I did not respect their values.
Therefore, I could never believe in discrimination between human beings and races.
I would like to apologise to all my friends and fellow athletes, who I may have insulted or shamed, the National Team, as well as the people and companies who support my athletic career.
Finally, I would like to apologise to my coach and my family.
