LONDON (Reuters) - Britain's defence ministry said on Monday that it was investigating how nearly 50 pages of secret military documents were lost by a senior ministry official and ended up at a provincial English bus stop.

The BBC reported that the classified documents - including some relating to Afghanistan and others analysing Russia's potential reaction to the passage of a British destroyer through the Black Sea - were found on Tuesday.
