                'Lone Wolf' Attacks Small-Scale But Hard to Stop

   by Al Pessin

   Militants around the world appear to be turning more and more to the
   type of apparent 'Lone Wolf' attack that hit Canada's capital, Ottawa,
   on Wednesday, and in Quebec province on Monday. As VOA's Al Pessin
   reports from London, such attacks are small-scale but often difficult
   to stop.
