SARAJEVO (Reuters) - Bosnia's mystery pyramid will now be probed and inspected by a team of experts from the U.N. Educational, Scientific and Cultural Organization.

"We shall send a UNESCO expert team to Visoko to determine exactly what it is all about," UNESCO Secretary General Koichiro Matsuura said in an interview published on Monday in Dnevni Avaz newspaper.

Amateur archaeologist Semir Osmanagic has caused a stir with his find, although local and European archaeologists denounce it as nonsense.

Geologist Aly Abd Barakat, an Egyptian researcher sent by Cairo to assist Osmanagic's team last month, has said that the Visocica hill did appear to be a primitive man-made pyramid of uncertain age.
