From Our Own Correspondent

A mysterious encounter with the sinister Colonel Tariq, thought to be from Pakistani Intelligence, is described by Aamer Ahmed Khan. Tim Whewell's in the Sinai Desert finding a roaring trade in rifles. A guided tour of Benghazi with Andrew Hosken: he is told that Colonel Gaddafi couldn't make the railways run on time -- he couldn't make the railways either! An acute housing shortage in Beijing is described by Martin Patience - it's meant people living in air raid shelters, bunkers and tunnels. And there's joy and some plum brandy in the foothills of the Carpathians as Caroline Juler joins a cheerful crowd of farmers at their annual measuring of sheep's milk.
