[Q]: (CNN) In 2004, Mostafa Salameh had a vivid dream: he was praying for peace on the top of a mountain. "I woke up sweating and I saw myself on top of the world," Salameh tells CNN. Back then, Salameh had no expedition experience, little money and couldn't have pointed to Mount Everest on a map.

[Q]: Last week it looked as though the Balkans would be plunged into conflict once again after two newly formed 'micro states' clashed over a strip of unclaimed 'no man's land'. Admittedly the war of words bore little resemblance to the strife which has torn apart this often restive corner of Europe down the centuries. The Kingdom of Enclava had claimed a patch of territory by the Serbian border - unaware the land had already been staked out a month before by the Principality of Celestinia. Celestinian interim chancellor of foreign affairs Endre Jos, a 39-year-old IT technician, said of the Enclavans: 'If they try to settle there, we will be there, destroying their game.'Kingdom of Enclava claimed patch of territory on Croatia-Serbia border - unaware it had already been staked out by Principality of CelestiniaCelestinia threatened to 'destroy' rival's 'game' in bitter territorial disputeBut Enclavans, from Poland, and Celestinians, from Hungary, have agreed to share 0.3 km sq patch by the Danube - same area as 43 football pitchesCelestinian spokesman: 'Encalvans are friendly, peace and freedom-loving people.
