MADRID (Reuters) - Army units were mobilised to help about 600 drivers who were stuck on a motorway in heavy snow as Storm Juan blanketed many parts of Spain, authorities said on Friday.

       Snowfalls left motorists stranded for hours on the N-122 road between Soria and Agreda in northern Spain so authorites said they had dispatched troops from a base in Zaragoza to help move the drivers.
