Dubai: Even as the authorities are moving fast to restrain the ugly Twitter war between two-weight former UFC champion Conor McGregor and reigning king of the octagon, Khabib Nurmagomedov, the Irish fighter has attempted to tacitly defend his rants that triggered the war of words.

McGregor, who only last week shocked the world by retiring from the sport after a 25-fight career, has attracted the wrath of millions after posting a tweet, with pictures, that insults Nurmagomedov’s wife and her faith.

The messages were labelled on social media as “racist” and “Islamophobic”, as Nurmagomedov and his wife are Muslim.

UFC president Dana White stepped in, saying the Twitter exchange had reached an “unacceptable” level, and that the “necessary steps were being taken”.

“The ongoing situation has escalated to a level that is unacceptable,” White said. “As such, we are taking the necessary steps to reach out to both athlete camps and this situation is being addressed by all parties internally.”

There’s bad blood between the fighters ever since Nurmagomedov defeated McGregor last October at UFC 229, in a lightweight contest that is believed to be the biggest and richest in the sport’s 25-year history with pay-per-view figures crossing the $3 million mark.

As the world reacted to McGregor’s latest shameful episode, the volatile Irishman tried to defuse the situation saying: “I want to move forward, with my fans of all faiths and all backgrounds.

“All faiths challenge us to be our best selves. It is one world and one for all.”

McGregor even suggested that his retirement should not be taken seriously: “Now see you in the Octagon.”
