London, July 25 (BridgeNews) - Europe's major stock markets came under more selling pressure amid the threat of a further deterioration in corporate earnings. The U.K.'s FTSE-100 benchmark index fell to its lowest level for two-and-a-half years, as a bad reaction to outlook comments in the telecommunications, engineering and banking sectors overshadowed some positive individual results from a handful of companies. At 1535 GMT, the FTSE Eurotop 100 Index was down 44 points, or 1.5%, at 2893 points.
