A war of words has broken out on Twitter between US business tycoon Donald Trump, the Republican presidential hopeful, and Saudi Prince Al Waleed bin Talal.

It all started after the Saudi prince hit out at Trump over his statement that called for a ban on Muslims entering the United States following the San Bernardino terror attack.

"@realDonaldTrump You are a disgrace not only to the GOP but to all America. Withdraw from the U.S presidential race as you will never win, (sic)" Prince Al Waleed, chairman of Kingdom Holding and one of the richest man in Saudi Arabia, posted on his Twitter account.

Earlier this month, Donald Trump, who is the leading candidate to become the Republican party's nominee for US presidential candidate, made his most racially charged statement when he called for a "total and complete shutdown" of the country's borders to Muslims in the wake of the San Bernardino terrorist attack.

The American Billionaire, not one to mince words, hit back by calling the  Saudi prince "stupid."

"Dopey Prince @Alwaleed_Talal wants to control our U.S. politicians with daddy's money. Can't do it when I get elected. #Trump2016, (sic)" Trump said on Twitter.

@Alwaleed_Talal @realDonaldTrump No, Prince, not a disgrace...He's a disruptor certainly. But that's part of his appeal. You'll get along.
