SBS presenter Scott McIntyre has been sacked from the broadcaster after posting a series of comments about Anzac Day on Twitter that were described as "inappropriate and disrespectful".

McIntyre, a soccer reporter and presenter, referred to some Australians marking Anzac Day as "poorly-read, largely white, nationalist drinkers and gamblers" on his officially verified Twitter account on Saturday night.

Sacked over Twitter comments: Scott McIntyre.

"Remembering the summary execution, widespread rape and theft committed by these 'brave' Anzacs in Egypt, Palestine and Japan," he wrote to his 30,000 followers.

"Not forgetting that the largest single-day terrorist attacks in history were committed by this nation & their allies in Hiroshima & Nagasaki."
