NATO's secretary-general tried Friday to ease Russia's fears over the alliance's upcoming military exercises in Georgia, saying they were not directed against Moscow. During a visit to Romania in a farewell tour as NATO chief, Scheffer said he hoped Russia would respond positively to NATO's invitation to send observers to the exercises.
