US industrial production fell in March, data released by the Federal Reserve Friday showed. Manufacturing output dropped by the most in a year while mining output continued to shrink, signaling a slump in economic growth in the first quarter, Reuters reported. Industrial production data decreased 0.6% in March, the Federal Reserve said in the release, after a 0.6% drop in February. The numbers, which are seen as broad gauge of output across US factories, mines and power plants, have noted falls in six of the last seven months.
