KABUL, March 11 (Reuters) - A biography of one-eyed former Afghan Taliban leader Mullah Omar says he lived near a U.S. base in Afghanistan for years, not in Pakistan as U.S. officials have said, exposing Western failure to track him down, but a spokesman for the Afghan president described the claim as "delusional".
In her book "Op Zoek Naar De Vijand (Searching for an Enemy)", Dutch journalist Bette Dam says Omar never hid in neighbouring Pakistan.
He lived in hiding just three miles from a major U.S. military base in his home Afghan province of Zabul, said Dam, who says she spent five years interviewing Taliban members for the book.
Omar's hardline Taliban ruled Afghanistan from 1996 until 2001, and has waged an anti-government insurgency since then.
Omar, who delegated effective Taliban leadership after 2001, appears to have acted as more of a spiritual leader, according to the book, and the militant movement kept his death in 2013 secret for two years.
He was wanted in the United States for providing a safe haven for al Qaeda leader Osama bin Laden, who masterminded the 9/11 attacks on the United States and lived in hiding in Pakistan, and Washington had placed a $10 million bounty on his head.
U.S. forces even searched his accommodation on one occasion, but failed to find Omar's hiding place, Dam told Reuters.
"The book underlines the failure of Western intelligence at a time when U.S. and Taliban officials are holding peace talks to end the 17-year-old war in Afghanistan," she said.
The U.S. Embassy in Kabul did not immediately respond to a request for comment. The United States has halted the disbursement of Coalition Support Funds to Pakistan due its perceived failure to take decisive action against Afghan Taliban militants operating from Pakistani soil.
Haroon Chakhansuri, a spokesman for Afghan President Ashraf Ghani, "strongly rejected" the book and it was a "delusional claim" that Omar lived in Afghanistan.
"We have sufficient evidence which shows he (Omar) lived and died in Pakistan. Period!", he said in a Tweet.
Amrullah Saleh, a former Afghan intelligence chief running in upcoming vice presidential polls, also dismissed the book.
"The so-called investigative report claiming Mullah Omar lived and died in Afghanistan is nothing but a manipulative piece of propaganda," he Tweeted.
In July 2015, the Taliban officially confirmed Omar had been dead for more than two years.
Omar's eldest son, Mohammad Yaqoob, said in an audio tape released in September 2015 that his father had been suffering from hepatitis C and died in Afghanistan.
Dam has previously published a book on Afghanistan and is a guest lecturer on Afghanistan at Sciences Po in Paris.
Dam's book was published in Dutch last month. (Reporting by Rupam Jain; Editing by Nick Macfie)
