London: In a significant revelation made by Osama Bin Laden’s son, Omar, it has been claimed that George W Bush invited him to the White House in the final days of his presidency. The efforts were taken up in a last-ditch attempt to track down the world's most wanted terrorist by US government.

The fourth son of the al-Qaeda terror network founder has claimed that he received a visit invitation from White House staff in January 2009 at his home in Doha.

"They invited me to accompany them to the White House, offered to defend, help and protect me, on the condition that I helped them find my father," he informed a Spanish daily newspaper.

But the 29-year-old said he refused because of filial duty. "I told them I was sorry but it wasn't something I could do. He is my father and I am his son," he said.

But the son who was once groomed to take over from Bin Laden later admitted that he had no contact with his father for almost a decade.

The younger Bin Laden claims to have renounced violence and walked away from his father's compound in the Tora Bora Mountains of Afghanistan, months before the attacks on September 11, 2001.

A spokesman for the White House refused to make any comments and informed that no detail can be provided as to whether such a thing happened or not.
