Oil slides, stocks drop; Paris attacks add to jitters

U.S. stock index futures hit session lows after the close on Friday after France was rocked by multiple, near simultaneous attacks around Paris. Weaker-than-expected U.S. October retail sales weighed on U.S. stocks for much of the day, with Wall Street capping its worst week since August, and dragged U.S. Treasuries yields to their lowest levels in a week. Friday's Paris attacks could add to market jitters, analysts said.
