White House hopeful Barack Obama's [Images] long lost brother has been tracked down for the first time living in a hut on the outskirts of the Keniyan capital, reports claimed.

Twenty-six year-old George Hussein Onyango Obama, the youngest of the presidential candidate's half-brothers, spoke for the first time about his life, which could not be more different than that of the Democratic contender for the most powerful post in the world.

'No-one knows who I am,' the younger brother of the White House hopeful was quoted as saying by the Vanity Fair magazine.

According to Italy's [Images] Vanity Fair, his two metre by three metre shack had a front page newspaper picture of his famous brother -- born of the same father as him, Barack Hussein Obama, but to a different mother, named only as Jael.

Embarrassed by his penury, he said, 'If anyone says something about my surname, I say we are not related. I am ashamed.'

'I live here on less than a dollar a month,' he claimed, adding 'I live like a recluse; no-one knows I exist'.

He has only met his famous older brother twice -- once when he was just five and the last time in 2006 when Senator Obama was on a tour of East Africa and visited Nairobi, Daily Telegraph newspaper said in a report.

According to the British daily, the Illinois senator mentions his brother in his autobiography, describing him in just one passing paragraph as a 'beautiful boy with a rounded head'.
