'Three Cups' charity to be investigated

The attorney general in Montana has started an inquiry into the charity run by Three Cups of Tea co-author Greg Mortenson after reports suggested Mr Mortenson benefited from money donated to build schools in Pakistan and Afghanistan.

The US news programme 60 Minutes alleged that Mr Mortenson's Central Asia Institute, based in Montana, took credit for building schools that do not exist.

The writer has denied the allegations, saying he stands by the book, published in 2006, which follows his mission to build schools across Central Asia.
